Postprocessing mpegs from AC3 to Stereo

[rkleckner]

I have been reading previous ffmpeg and zprocess2 posts and can't quite get this right. Generally, here is the logic I am trying to accomplish:

GBPVR records DBA show using HVR 1600 QAM (Comcast USA).

if ("Globe Trekker" in title, 480i) or (channel = 77) then
ffmpeg original.mpg -> target.mpg
replace original.mpg with target.mpg (to playback on MVP)
else if Show_HD (720p, 1080i) then
ffmpeg original_HD.mpg -> target_SD.mpg
replace original_HD.mpg with target_HD.mpg (to playback on MVP)
else
do nothing (NTSC Analog)
endif

I tried recent MVPMC dongles, but still have auto sync problems. I want to stay with mpegs and standard GBPVR dongles and I have already successfully converted individual files using command line ffmpeg and the audio sync has been spot on (my goal).

I rarely watch real time shows so overnight post conversion is okay. Is anybody doing this using Postprocessing.bat? Where should I be focusing my attention?

Which mvpmc version? Released a new alpha donlge version on Oct14 which is said to fix some audio sync problems.

I used the Oct 14th version of MVPMC, still had some audio sync and remote control problems. I also wanted to mention that I use comskip. Most shows are in 480i digital, so if I could just convert the ac3 to stereo and replace the file, I would be happy.
