Archived from groups: rec.video.desktop Hi all, How can I remove CPRM-protection from a DVD-RW???? I made my first recordings using a Maxell DVD-RW, with my brand new Pioneer DVR-220S DVD-R recorder. Now I want to ripp the files from the disk and edit and author the material with my PC to a DVD+R.
But this CPRM-protection is keeping me away from my own recordings! What the heck is going on here? I've tried (almost) everything: making an ISO file from the DVD-RW with DVD Decrypter to HD, viewing that ISO with ISOBuster, I can see the files, but I can't copy them, why I don't know, the program is fully registered and paid for, it must be that CPRM that keeps me from my own files. I was (probably) wrong to buy 3 CPRM protected DVD-RW's, I did not notice, I always use DVD+R disks with my DVD-NEC2510 burner on my PC. But now I have to buy DVD-R because Pioneer won't accept DVD+R, and now this CPRM creeps up. I will buy in the future DVD-RW,s.without. CPRM!
If they even exist. Please, help me find a way to get my files of those CPRM disks. I think this whole CPRM is a bad idea, nice for extra protection on DVD-movies, maybe, but not for normal home use.

I'm curious about CPRM too. It just came up for us at work. We bought some one off stand alone DVD recorders to free up our encoder. The idea was to give the client a DVD to walk with or make one DVD and duplicate on our tower DVD dubber. But DVDs made on the stand alone recorder will NOT duplicate.
Can't even peek into the failed copy with DVD Shrink. Goggling around on this subject it seems to be a function of the DVD recorder AND the particular DVD disks.
Is a work around simply a matter of finding DVD disks that don't have CPRM already burned on them? All we want to do is send a composite video and audio signal to the DVD recorder (content we own) and make a DVD that we can duplicate.

Just demuxing the files from the RW using DVDDecryptor in IFO mode didn't work for you, either? - In DVDD I can't even see the files! The DVD-RW from the Pioneer DVD recorder I made to test, I forgot to finalize, that's the trouble.
I did finalized with DVDD, but still those files are unreachable, and one was missing, when I looked with ISObuster. I will make a new test recording and finalize on the Pioneer, let's see, if that works, if not, it's the new CPRM that screws things up. Then I will use a DVD-RW.without. CPRM factory-burned into it. And then try again. If that fails too, I will be very angry, and return the Pioneer DVD-Recorder, because it will be useless to me. Thanks for you attention.
BTW, it seems, according to Pioneers engineers I talked to, that you cant even copy the data from the HD from a Pioneer DVD/HardDrive recorder with firewire. Is that known to anybody? Or are they wrong?

The only way around CORM is to use a DVD - ROM player that doesn't have the chip inside it that recognizes license codes. The early 2X DVD drives that were built before all the video devices were chipped is probably a good bet for you. They are slow, and probably won't recognize DVD-R or DVD +R disks, but they can still be used to output a clean video stream from commercial DVD disks. It is for that reason I didn't get rid of mine when I 'upgraded' my drives all those many years ago. That ancient clunker is worth its weight in platinum.

Thanks, but I solved my problem, I totally erased the DVD-RW+CPRM with Nero, and made another test recording on the Pioneer DVD220S and finalized the disk, the result was a 'normal' DVD I could ripp with DVDD, and further process with my usual software. The main reason I'm doing this, is that in the future I want to use a DVD-standalone Recorder instead of my computer, to capture. Now it seems to work. And the good news is that Pioneer now makes DVD-standalone Recorders that can handle both DVD-R and DVD+R.
Hi, folks, first time poster here:) A little bit of background first: I much prefer older movies. TCM/AMC are my main sources.
Commercially available DVDs with older content are a less attractive option in part because they can get quite expensive and in part because their selection is still poor compared to TCM/AMC. There are exceptions to the rule, of course. I am a consultant who is on the road an awful lot and I used to tape (VHS) movies whenever I had time and cable access. However, eventually it got to be rather tiresome, what with travel and pre-programming and juggling tapes and other hassles. Now that reasonably priced DVD recorders with built-in hard drives are hitting the market, I am starting to look into buying one. The idea is to select everything from the TCM and AMC schedules that I am interested in once every few weeks and have it to the hard drive, then dub it to DVD-R whenever I find myself at home and use the DVD-Rs on the road and/or when I am at home.
The 'TV Guide' style programming mechanism available in Panasonic DMR-E85H sounds like it will make the whole process a breeze, especially when you add a 120Gb hard drive and better recording times than earlier models. There is only one problem - bear with me if I am barking up a wrong tree since I am a DVD-R newbie - and I found it in the DMR-E85H manual. On page 14 it states. Quote: For most source material, there are no restrictions.
However, CPRM can be applied to digital cable/sat/OTA signals, preventing you from duping a show, movie, or event to a DVD-R for archive purposes. You would be able to copy to DVD-RAM, but the source is then automatically deleted from the HDD. Moreover, DVD-RAM is not compatible with most stand-alone DVD players. So with CPRM getting more and more likely to become an issue in the near future (not earlier than July 2005 in the US according to the last FCC ruling, I believe), does it mean that: 1. Once CPRM flags go into effect, all DVD recorders will only be able to dub CPRM-flagged programs to DVD-RAM and not DVD-R, or 2. Some DVD recorders like Panasonic E80H and E85H will only allow DVD-RAM dubbing, but other recorders will also allow DVD-R dubbing? If (2) is the case, then I may want to reconsider getting a Panasonic and go with some other brand instead.
If (1) is the case, then, um, I may have to re-evaluate the whole thing:( Granted, if I get lucky and only premium channels like HBO/Cinemax choose to use CPRM, then I won't be among those affected, but it would be a $500+ gamble. I haven't been able to find a comprehensive explanation of CPRM-related issues and I don't know much about DVD recorders in general aside from what I have read on the Internet as part of my search for that 'perfect DVD recorder', but here is my current understanding, quite possibly flawed. What is CPRM?' CPRM stands for Content Protection for Recordable Media.
It is one of the recent attempts to allow the owners of certain types of intellectual property (movies, music, etc) to limit duplication of digital copies of said property. Thus, a broadcast may be marked as either 'copy free' (no limits on duplication), or 'copy once' (can make one copy) or 'copy never' (can't make copies at all). What types of media does CPRM affect?
There were some attempts to incorporate CPRM in computer hard drives a couple of years ago, but it looks like they have been abandoned, at least for now. The impact is likely to be felt in the DVD recording arena, i.e.
DVD-R, DVD-RW, DVD-RAM, etc. It is rumored that DVD+R(W) may be harder to make CPRM-compliant (?) 3. What kind of piracy is CPRM supposed to address?
CPRM is not expected to thwart professional pirates who make a living duplicating and reselling thousands of DVDs. It is aimed at the causual user who may want to make multiple DVD copies of certain shows, movies and so on for backup or family use purposes. It may also affect people who are into DVD trading on a small scale, but are not sophisticated enough to defeat CPRM or are not willing to expend the time and the effort necessary to do so. How does CPRM work?
All consumer DVD-Rs (DVD-R(G)s, to be precise, which is the inexpensive variety aimed at the mass market) have a small area close to the DVD hub that is known as the BCA, or Burst Cutting Area. The data in this area is pre-recorded at the factory and DVD recorders can't change its contents, but can read what's written there.
CPRM-compiant DVD disks (pretty much all of them at this point, I believe) have a unique ID recorded in that area at the time they are manufactured. The ID can't be altered and, since it's unique (no two disks with the same ID), it can be used to scramble and descramble data on disk. When a CPRM-compliant DVD recorder is told to create a CPRM-protected disk, it first reads the ID from the currently inserted disk and then uses it to scramble (encrypt) the data that it writes.
When a CPRM-compliant recorder tries to play the data back to your TV, it reads the ID from the BCA area and then uses it to unscramble (decrypt) the data as it reads it. So what happens if a CPRM-encrypted disk is copied to another disk? If a CPRM-encrypted disk is copied to another disk, that other disk will have a different ID in the BCA area, therefore at playback time the descrambling process will fail and the disk will be unreadable. When will CPRM go into effect? CPRM has been used in Japan for some time and its use was expanded dramatically in May 2004. In the United States, the legislative and regulatory processes are still going through the motions, but it looks like the FCC has given broadcasters a green light to start using CPRM after July 2005. Will all broadcasters start using CPRM after July 2005?
Unknown at this time. Will CPRM-enabled digital broadcasts be actually encrypted so that non-CPRM-compliant recorders won't be able to record them at all? It would appear that at first CPRM-enabled content will be simply flagged to tell CPRM-compliant recorders to restrict dubbing, so non-compliant recorders will ignore CPRM flags and record normally. However, most DVD recorders sold in this country are already CPRM-enabled and if you want to get newer, better models, you may not have much of a choice.
