AC3 Joining Problem

[borg754654]

Hi!

I have a problem and i do not know a solution. Maybe you can help me..
I rip my DVD usually with two soundtracks. AC3 (Dolby Digital) in my language and the OST with VBR. Know I want to add the Dolby Digital Trailer in front of the movies (you know these neat trailers). But when try to join the Files, I get something like "Cannot join, because AC3 not compatible". (I get this error EVERYTIME, even with only one soundtrack).
How can I let some tool (what tool) code to make compatible AC3?

Assuming that they are the same bitrate, you can do it one of two ways:
1) Make a lst of the files, open that up in besweet, and set it to payload.
2) or open up all the vob files in dvd2avi that you want and demux an ac3 as you save the project.
