Hi, this question concerns compressing and editing TV programs recorded in Windows 7 Media Center. My library is generally in XviD AVI format so this is what I am trying to achieve. After a lot of tinkering and messing around with various software, the best process I have come up with is the following... 1) Convert WTV to DVR-MS using Windows 7. 2) Convert DVR-MS to MPG using DVRMSToolBox. 3) Convert MPG to XviD AVI using AutoGK. 4) Remove ads using AVIDemux or VirtualDub. However, where this process works perfectly with some files, it doesn't with others and I get audio sync issues about 25% of the time. Generally speaking the audio problems happen at Step 3. This doesn't surprise me as this is the main encoding stage, but it is frustrating that some files work and some don't when all the files are recorded on the same computer using the same format and settings. I cannot for the life of me figure out a pattern as to which ones have problems. It isn't files recorded from a specific channel or anything like that. All processing is done on the same computer so it isn't a hardware issue. My question is two-fold: 1) Has anyone got any idea why the results are haphazard? 2) Can anyone suggest a better, more reliable, process? Many thanks in advance.
