I never use DVD-RW disc so I don't know the solution to your problem. You can try and burn the data to a DVD-R disc and see if that's the problem. I always use DVD-R so everything works for me.

You might also try the disc on a different DVD player and see if the DVD-RW disc will play in another DVD Player. Not all DVD Player are created equal.

I have had problems with CPRM. Well I didnt know there was any until the player gave me an error. But the disk worked just fine on the computer. So now I just use the RW disk for data rather than movies. The -R disks I use does not seem to have any of the authoring stuff in it.

What is Content Protection for Recordable Media?
Sometimes analog or digital broadcasts (typically in Japan) are identified to allow only one copy to be made by a viewer and by using the Content Protection for Recordable Media (CPRM) system, such material can be encrypted and recorded once to a writable DVD disc. As it is currently marketed, CPRM is an option found only in some consumer electronics (CE) DVD recorders that write DVD-RW and DVD-RAM discs using the DVD Video Recording format (DVD-VR). This allows material specifically flagged “copy once” to be written to a single disc but prevents that disc from then being further duplicated. This is accomplished by binding the content to the particular disc through encryption employing, among other things, a code (media identifier) unique to each writable disc compliant with the CPRM system. This one-off code is inserted at the factory into the special Narrow Burst Cutting Area (NBCA) of a DVD-RW or Burst Cutting Area (BCA) of a DVD-RAM disc and, as such, cannot be duplicated by a DVD recorder.

Be aware that not all DVD players, drives and recorders that play or write DVD Video Recording formatted (DVD-VR) discs are compatible with CPRM and that not all blank DVD-RW and DVD-RAM discs are equipped with the NBCA or BCA necessary to handle CPRM content. If in doubt, consult with the hardware or disc manufacturer.
