Anyone knows one?

VirtualDub(Mod)

I hope you know that AVI is just a container?

Something other than VirtualDub which returns error -1 when I try o save to XVID?

i think some of the later versions of virtualdubMod are unstable, but they should be loading xvids properly, unless there's something up with your system.

i have no idea what error -1 is.. but generally if VDM doesn't load something it's not going to load in anything that uses VfW interface.

if you're up for spending a lot of time, you can use GraphEdit and manually hook everything up to export an avi file, but this is more unstable than VDM by a long way.

Are you sure that you are not cropping to odd resolutions with virtualdub? I think this is what causes this error or resizing to strange resolutions perhaps? If you are using filters in virtualdub you really shouldn't you should be using avisynth 2.5 and virtualdubmod latest ones seem stable.
