Finally managed to get it onto VideoHelp.. YAY! it was accepted by SourceForge like a week ago too, double YAY!

Basically it batch converts OGM/MKV to AVI with subtitle and audio, you can select which stream and resize the screen as well as change bitrate and codec

as of now the only audio format it encodes to is mp3

fully open source! for both Linux and Win32(Has GUI)

thanks for your help
