Spent a bit of time trying to get it out of the asf format so I could do some editing, and convert to xvid.

I initially used tmpgenc, because virtualdub wouldn't support asf. and after doing some searches for ones that do, those just gave me errors.

So with tmpgenc, it said the fps was 30. which I thought should be 29.97 (I tried both anyway). The resulting conversions had audio and video synching problems. There were also quite a few very noticable studders throughout the video.

That's pretty much it, just the studders and synch in the resulting xvid encode. Everything is good when played back in it's asf format, so the original is fine.

So I basically would like to know what causes these 2 issues and how to fix them. Thanks.

how to fix themWhy not go back to the original source that you used to create the .ASF and DIRECTLY create an XviD file?

Erm, because the original source IS asf? That suggestion is pretty much given man, jeez.

Just wrap it in an Avisynth script:

DirectShowSource("foo.wmv", fps=29.97, convertfps=true)

Hey, that worked perfectly :D Had to read an FAQ to find out vobsub was screwing around with the function though ;P

Thanks.
