I've been following this thread for a few days, and hoped to try out
the scripts sometime this week. However, after seeing this post it
appears as though I need some clarification.

If I understand correctly, if I have already transcoded programs from
MPEG2 (recorded from PVR250s and/or PVR500) to MPEG4, then I cannot
use these scripts to burn to DVD. Is this correct?

I guess what I need to do is start recording programs with a different
profile, so that they will not be automagically transcoded, if I want
to burn them to DVD. Please confirm...
