I am no newbie when it comes to video editing and that sort of thing. However, I am sick at the moment and rushing to complete a project for a friend. Can someone please point me in the direction of a simple utility that can; mux 2 AC3 files with an M2V video stream and output to a MPEG file? I tried MPEG Tools in TMPGEnc XPress but it only muxes 1 audio and 1 video track. Virtualdub does what I want - but only for AVIs.

The important thing to note is that the video isn't DVD-compliant. I just want to do this for an MPEG file to be viewed on the PC. I don't want to have to re-encode or scour through complex programs. There's gotta be a program made solely for this purpose, I know it. I just can't find it, wherever it is.

Can somebody help me out? Thanks in advance.
