I downloaded video conversion software from appletvconverter . com site. The program works nice for convering my AVI and MPG files, but it doesn't work for the rmvb files I downloaded from limewire. When I load the rmvb files to the software, click "convert", it has no any response. Any ideas? I am running Mac OS.

Since it's free version, maybe there are some restrictions for that.
Is there any support team for that utility?
