Russian company STOIK Imaging has announced the release of STOIK Video Converter, a dedicated video conversion, processing and enhancement suite. Available in Free and Pro editions, STOIK Video Converter Pro can convert between AVI, DV, MKV, MOV, MPEG 1, 2 and 4, and WMV formats in all possible combinations.
It's a pretty good video converter for the price, I only wish it had some more features.
