If you use the DVD multiplexer of DVBCUT (default choise), the files you create with DVBCUT are already valid (hopefully...) VOB files. I can't give a warranty for the DVD muxer of DVBCUT, but my experience so far is, that the generated VOBs always play fine if there is no error output on the console in which DVBCUT runs. (For this purpose, it's better to start DVBCUT from some console or xterm.) If you get lots of warnings (muxer error), then something is going wrong in the muxer and the resulting file might have some problems. The point is that DVBCUT preserves the time stamp within the video and audio streams one-to-one. Therefore, even if they are damaged blocks in the video or audio stream, the time relationship afterwards is still okay. I could imagine that that TMPGEnc tool does some demuxing and muxing steps during which the original timestamps are lost. > Question: should I suspect that TMPGEnc is buggy, and that a different DVD > authoring system would be better at maintaining sync? or I'm always using 'dvdauthor' to create the DVD image directory from the VOB files. It can be used as a simple command line tool, or you can use an xml language to describe more complex DVD layouts. > Should I give up on the idea of storing captured TV programs 'directly' to > DVD because imperfections in the recorded stream will always lead to loss > of sync somewhere in the processing chain? or I hope not. That was the original idea of DVBCUT, to use it like that. I know there are some bugs in it, which cause especially problems with slightly corrupted files. Also there must be some problem inside the DVBCUT muxer, but it works fine for a good fraction of cases. Just my 2 cents...
