How do you combine seperate mpg audio and video streams?

[Amethysque]

I downloaded an mpg file that was corrupted, so I had to use bbdemux and take it appart. The extracted video and audio streams are fine, but how do I reassemble it into one file? I tried using MPEG Multiplexer, but it kept crashing or it would do wierd things. Thanks?

dude, just open both in qt, cut or copy one of em, and "add" (or "add scaled" if they exact length) into the other, then save it..
(if u save it u will have to keep the orig files, otherwise export it out as a new mpg, but that takes a while..

i found that the simplest and most efficent way of doin it, and no probs eva.
