How Do I Replace One Soundtrack With Another, mp4/aac file?

[mcompton69]

Hi all, not been here for ages, its always such a great forum, hopefully someone can help me.

I have received an mp4 video file, which comprises 1 video stream and 1 audio stream (the latter is a 2 channel aac). I then received a DTS soundtrack which i need to replace the original with.

How do I do this and what tools do I need?

Thanks in advance.

A mp4 multiplexer like yamb, mymp4boxgui, mp4muxer.

Buzzin - will give them a try!

- I have tried yamb already, but none of the options in the gui would do what i wanted, not even demux.

PS - Baldrick, what u think of your SSD? Was it worth the investment over an hdd? Does it support trim? Does it get slower over time?

I have tried both Mymp4boxgui and mp4muxer and both have produced a file almost exactly the same as the original video. No errors reported. Any ideas what the problem might be?
