I ended up giving up on using nuv2disc. All of the tools I was using to process
PS recordings still had issues after converting the recording to PS using ts2ps.
The next release of KnoppMyth will have mythburn automtically integrated, so I
decided to see whether that worked. The use of Project X seems to be the
clincher here. I didn't look into it in detail, but I just made a TS test
recording selected it for burning with mythburn and it went ahead and created
the iso no problems. I manually burnt this iso to dvd using growisofs and it
played fine in my dvd player with no audio sync issues.
