I have a Philips DVDR-72 that was purchased "refurbished" from Philips direct about a year ago.
Just recently it began to have "disc error" messages following the step to "finalize" a disc.
This occured using Ritek brand DVD+R discs,
note..however over 50 of them were recorded from the orginal 100 pack spindle without ANY problems.
I too wanted to determine if it was the "media" itself or the DVD recorder. But in addition, I thought it may of even been related to a problem with the orginal source movie (protection or something)
Here's what happened:
First movie (M1):
Took the disc with "disc error" / "unknown data" and used PC to copy it with Roxio Easy Media Creator 7.0.
(a copy automatically "finalizes" or "closes" the disc, which the player was unable to do).
Using "creator", the DVD "folders and files" were copied TO the SAME brand media (Ritek).
The copied disc DID play on a DVD player (portable Polaroid player, not Philips),
HOWEVER it had video and audio skipping after the 3rd chapter.
Next, tried a DIFFERENT movie (M2):
This also resulted in the same exact "disc error", and was determined the
movie used was not a factor (as assumed for M1).
The 2nd movie (M2) was copied with Roxio CD Copier TO a "Memorex" disc instead.
This disc played PERFECTLY in the portable DVD player. (excellent!)
I then took the first movie (M1) and copied that one to a Memorex DVD,
(again using Roxio CD Copy), and it ALSO played perfectly.
This reiterates what the orginal poster stated (thanks for sharing).
I did try putting the Memorex disc in the Philips DVDR72, and then the M1 and M2 disc error CD's, but they still wouldnt play.
All in all I went through a TOTAL of (8) discs to get (2) movies that play.
Still have yet to determine if my DVD recorder is biting the dust. My best guess is that it is...since CDROM lasers don't last very long (I have had 3 go out in the past).
One thing for sure, CD/DVD recording is almost rocket science! :eek:
