I learned early on to *ALWAYS* do this! MythArchive is a useful tool, but its
failure rate is rather high -- probably in the 25% range for me. Issues
include audio sync problems and flat-out truncated recordings (45 minutes in,
10 minutes out). I've even got a symbolic link in my videos area that points
permanently to the mythburn.iso file in the archive area. That way, I don't
even need to move or copy the image file when I'm done; I just go into
MythVideo and check it out. If it's OK, I burn it; if not, I tweak things and
try again.
That said, MythArchive seems sensitive to certain types of problems, and it's
possible that some people will generate problem files a lot whereas others
won't. MPEG-4 seems prone to producing audio sync problems, for instance.
Transcoding to MPEG-2 using mencoder can minimize those problems, but this
sometimes results in truncated videos on the DVD (the mencoder-created file
plays fine in MythVideo, but dvdauthor chokes on some mencoder-created files
and the MythArchive scripts ignore this, resulting in a short recording).
