Problems encoding DivX with AC3

[kiffgj]

I am trying to encode the movie "Exit Wounds".
It appears that the soundtrack in split into 2 files.
The intro for the first 3 mins or so is s 2 channel 192kbs AC3, it then switches to a 5 channel 384kbs for the rest of the film.

Does anyone know how I can use both AC3 files sequentially?

I thought of removing the first part of the film, but the 2 channel soundtrack actually ends after the films starts for real.

Many thanks

What program did you use to rip dvd to hard disc. I don't think it was smartripper.

Use Smartripper and you will get a copy on your hard drive without first part of the movie - an intro, as I suppose

I am using SmartRipper
As I said before, the "intro" soundtrack (2 channels) actually runs into the first minute or so of the actual film, then changes to 5 channels.
