I've have about a hundred DVD-sVCDs (480x480 MPEG-2 video with 48KHz AC3 audio) on Memorex DVD-Rs that I created with my Pioneer 106D (firmware v1.07). I authored them with Mediachance DVD Lab v1.2 and used the ASPI module to burn them. The files played fine from my HD using PowerDVD prior to burning the DVD-Rs. There was no indication of any error at burn time. I've now discovered that I'm having difficulty playing any of them.
I've tried several stand-alone players and several DVD-R drives in my PC and none of them will play a movie all the way through without locking up. The movies generally play about half-way through before the trouble starts.
When I try to copy the DVD files to my HD, I get all the IFOs and BUPs with no problem, but get CRC errors when the VOBs begin to copy. I'm running Window XP SP2 with all the available updates.
I've tried to recover the data using Naltech DVD Data Rescue v1.2. After about 8 hours it manages to produce files of the correct size on my HD, but they don't play well; i.e., there are errors in the files on my HD. Yes - I am 100% sure that the files played just fine before I burned them to the DVDs.
Interestingly, I've tried using the same process (DVD Lab/ASPI) to burn Memorex DVD+Rs and they work like a champ in all my players and drives.
Bottom line: I have about 200 movies that I will lose if I can't figure out a way to recover the data from my DVD-Rs. Any suggestions would be greatly appreciated!
