I was using a philips DVD8631 and could not copy a (unprotected) DVD using Nero's copy or DVD Decrypter.
Hearing all of the comments about what a poor drive this is I have had DELL replace it with an NEC3530A. Sadly, I am having the same problems.
As a test I have grabbed an ISO using DVD Decrypter from an unprotected DVD-ROM (which is DVD-VIDEO; it has the AUDIO_TS & VIDEO_TS folders.) I then burn the image onto a DVD+RW (don't want to waste DVD+R until I succeed using rewritables!) It works in the burner, but my player (which plays the original OK) won't wear it.
The player is a Samsung DVD-P147 which claims to support DVD-R, +R, DVD+RW, -RW "depending on recording conditions". It also states in the manual that it supports DVD, VIDEO-CD & AUDIO-CD.
I have tried re-flashing to Liggy's v3.01 firmware so that I can try using the bitsetting function. Can I simply change the bitsetting so that DVD-ROM is written to DVD+RW & DVD+R then erase and re-burn? Tried this and still no luck.
There seem to be a lot of people having the same problem (but I'm only backing up an unprotected Video DVD.) Can anyone provide me with a magic bullet?
Oh, BTW: Media ...
(TDK DVD+R) RICOHJPN R02 (003) - worked* using the old Philips
(Verbatim DVD+RW) MKM A02 (000) - doesn't work
(SONY DVD-RW) - doesn't work
(IMATION DVD+RW) - doesn't work
Have been trying to get this sorted out for weeks so I hope someone can help!
