MKV with AVC video to AVI

[minnino]

I have a MKV file that has (from what mkvtoolnix tells me) "V_MPEG4/ISO/AVC" as its video. What I want to do with this file is make it an AVI with no audio or subtitles. I know how to do that with VirtualDubMOD, but when I use that to open this MKV file I get this error:
"Couldn't locate decompressor for format ÿÿÿÿ (unknown), VirtualDub requires a Video for Windows (VFW) compatible codec to decompress video. DirectShow codecs, such as those used by Windows Media Player, are not suitable. Only 'Direct stream copy' is available for this video."
After I say OK to that window it gets into VirtualDub fine, but there is no video. If I try to play the file, or seek the time the program crashes with these details:
"An out-of-bounds memory access (access violation) occurred in module 'VirtualDubMod'...
...while running thread "Processing" (thread.cpp:120)."
What steps can I do to fix this? I am sure there is some simple way to resolve this since I dont want subs or audio, just an AVI file. I would much rather like to be able to cut pieces out of it with VirtualDub then turn it to AVI, so I dont have to do the whole file (350MB) I only need a few clips out of that whole file. If anyone out there has some advice for me i would love it. Ive been looking all over reading up on things, trying so many different programs to fix this problem. Thanx
