I'm trying to rip videos from DVD+Rs of home movies that were dubbed from VHS to DVD on a Sony RDR-VX560 VHS DVD recorder. All work fine except for one. This recorder has multiple recording modes (HQ, HSP, SP, LSP, ESP, LP, EP, and SLP). It says when in a recording mode other than HQ, the recorder compresses the audio/video before recording. The longest SLP mode has a capacity of 14 hours 28 minutes on a regular 4.7 GB DVD. HQ (high quality) is 60 minutes, SP (standard mode) is 120 minutes, and there's 5 more modes after that with increasing amounts of compression and longer recording times.
I think the DVD I can't rip was made in one of the longer play compressed modes (I made these DVDs years ago). It has more than 2 hours of video on it. All DVD players I've tried it on can read it, but MakeMKV can't. I get a lot of errors like:
The source file '/VIDEO_TS/VTS_01_1.VOB' is corrupt or invalid at offset 96256, attempting to work around
then a message:
Too many AV synchronization issues in file '/VIDEO_TS/VTS_01_1.VOB' (title #-) , future messages will be printed only to log file
If I ignore the errors and try to continue, I get files that Windows Media Player can't play correctly. In one case, all the audio is near the end, and near the beginning, video comes out distorted, running much too fast. For other files (there's several titles on the DVD), the windows media player simply closes without displaying anything. This is on Windows 11.
I have 2 copies of this DVD, neither work in MakeMKV, but both play on regular DVD players. The 2nd copy was made on my computer by creating an ISO image of the original, and writing that to another DVD from my computer. Both DVDs produce the same errors in MakeMKV, so I don't think this is due to a damaged disc.
Any ideas on what's causing this, or ways to fix it? It seems like MakeMKV can't handle the compression that was done by the Sony DVD recorder.
