Converter Programs?

I was wondering if there are any other programs I can use to convert 2 files?
I was using TMPGEnc Plus recently to convert my rmvb file and wav file so the two turn into one m2v file. But recently the program started saying that the rmvb files were unsupported or could not be read. I was wondering if there are any other programs out there that I could convert 2 files (EX: rmvb + wav = m2v or mpg like file), it would be lots of help if someone could give me a program. I’ve tried Virtual Dub but that doesn’t work. Any others would be great.

Thanks :slight_smile:
