    Ogg is an audio format. I'm afraid you cannot convert it to AVI format.However, there are many software can convert mkv to avi, and I think winavi video converter is one of the best. You may learn some more details from its homepage http://www.winavi.com

    winavi is a little to fickle for me, most of the stuff i convert are more main stream : divx /xvid avi but for mkv and ogm avi2dvd is a fair substitute

    Ogg is not an audio format. It is a container format and it can contain video in the form of theora. Some people seem to get confused since by far the most common use of ogg is to store vorbis audio. ogg != vorbis though.

    Also ogm != ogg. It is a hack/extension to ogg created by Tobias some years back (and not updated since then) to add support to store store XviD video (as well as other VfW compatible video streams, ACM audio streams and subtitles) and vorbis audio.

    Of course it is possible to convert ogm to avi. Fact is that ogm video is always avi compatibile. Just the the audio tends to be vorbis and vorbis in avi is a bad idea (why Tobias created ogm). So all that is required is to remux the video and re-encode the audio. Something like: mencoder.exe -ovc copy -oac mp3lame -noskip input.ogm -o output.avi

    There are also numerous GUI's such as alltoavi.

    Mkv is tricker since the video is not always avi compatible. Also mkv supports VFR (Variable Frame Rate) where as avi is CFR only and when you assume something is CFR when it is infact VFR. You loose sync.
