DRM on blank DVDs

#1

Recently I bought a 10 pack of That’s DVD-R DLs. The eBay seller offered two types of this product, one which was just that and another that had “CPRM” inthe description.

I literally did not see the distinction until after I had bought the discs (my own fault primarily) and didn’t think much of it until a couple of hours ago.

So I checked up the acronym on Wikipedia and I found out that CPRM = Content Protection for Recordable Media … i.e. DRM :Z

#@+% that. I #@%&ing HATE Digital Restrictions Management. Yet what have I done :doh:

What exactly does CPRM on a Blank DVD mean, and if there’s some kind of DRM nonsense, can I bypass it or prevent it from interfering with my burn?

Hi,

if I understood correctly, then this CPRM thing mostly affects standalone DVD recorders, not computer drives (but which also support CPRM).
I don’t think, this “ability” will affect your burns. I’d be more concerned about the compatibility of that media with your drives :wink:

I just checked, it’s interesting, my DVD-RAMs have CPRM and my blank CMC MAG E01 doesn’t have anything showing. I checked this in CD-DVD speed

Of course, CPRM can only be supported by DVD-R* media.
It is required by standalone recorders in some regions, like Japan. It will not make any difference if you use a PC.

(The only difference is that CPRM capable media (often advertised as “For video” while incapable media is sold as “For data” media) may be more expensive.)

Michael[/QUOTE]I already know my Plextor/BenQ won’t like it, I had already decided to use my Optiarc 7203a with these.

But it won’t encrypt my burn or anything, or if I opt to copy the burn from these DLs to another DL in an img transfer or disk clone kind of situation, I shouldn’t expect problems?

Hi. I have a Panasonic DVD-RAM and it contains CPRM. Other media that I have, is a DVD-RW Intenso that also has CPRM; in my DVD player, it plays fine with no problems. I have never seen a DVD-R that has CPRM.

Hi juancdg, I’m looking at your drives listed. The optiarc drive, didn’t Sony buy them out about a year or so ago? I read some bad reveiws about the drive Sony added their name to. Correct me if I’m wrong.

I think that: Optiarc = Sony+Nec.

OK yeah your right, I was buying at tigerdirect at the time when Sony/Nec drives were on sale. I almost got one but the reveiws made me change my mind. That LG you have that reads damaged dvd’s sort of sounds like the Philips burner that read/writes disc’s that mt two Plextors have problems with, but it is a slooow burner.

Update:

I am nearly through this spindle now, and I’m going to have to use a DL for a DVD-Video burn, which means I may have to use one of my CPRM’ed TYG11s for the job.

I am satisfied that CPRM thingy has no implications for use with data, but is there anything (DRM related) that I need to watch out for burning a video project to CPRM discs?

CPRM only affects DVD recorders, not burning on PCs with standard drives:

You dont need to worry about CPRM unless you have a TV capture board and want to record something from TV with the copy restriction signal on it (like digital TV in JP) on the PC and then later burn/move to DVD.
