I am using the following process for achieving the same as you want:
1. capture into mpeg2 using PVR250 at 6000kbps
2. myth automatically runs commercial  detection 
3. I open video in myth player and press "E" then "Z" which starts editing and 
loads detected commercials  
4. I review commercial cuts and change if needed
5. encode using nuvtranscode into DVD or whatever 

I always have perfect sync and also encoding offline is always much better 
then hardware encoder of PVR250: I can fit about 5 hours of video on DVD with 
decent quality.

I was using dumb AVI card before but I had a lot of problems with sync so 
PVR250 is the way to go.
