The original PVR-250 recording--even if it used the DVD Special 
profiles--is still missing DVD NAV packets, so you do have to process it 
(minimally) before burning.  Can be done with replex, or--if you want to 
cut commercials--with something like avidemux2.

The big problem with doing this (either with replex or avidemux2) is 
that you tend to lose A/V sync.  Common wisdom on the lists seem to 
indicate that ProjectX can fix the problems, but I have noticed spurious 
A/V sync errors in my recordings processed with ProjectX (instead of 
gradual loss of sync resulting in a noticeable difference at the end of 
the recording, I have 5-10 seconds of sync offset 2-3 times per hour 
recording).  Don't know how many of the others who have just begun using 
ProjectX have actually watched their processed videos to see if they 
have problems too, but I didn't get any responses when I asked before.
