add second ac3-stream to divx

[Arcon]

i hope i've chosen the right forum to post my question. but i think virtualdub might be of help for this task.

i've got a 2cd divx-file with an ac3 audio stream and i want to add a second ac3-stream so that i can switch between the languages with microdvd or morgan stream switcher. the problem is that i've taken the second ac3-stream from another 2cd release that has been split at a different point. and i have no idea what i need to do to adjust the ac3-file so that it will match with the splitpoint of the video.

do i have to join the ac3-files first to split it afterwards at the right point? and which program should i use to add the stream to the video? is virtualdub or graphedit able to do all this at once? maybe i should join the videos and the ac3-files, mux them together and split the new avi afterwards? as you can see i'm pretty irresolute right now. please give me a hint which solution might be the easiest.

thanks for your help,

i would do this:
-load first file of second movie,append second file,audio to direct stream copy,save wav (you will get the ac3 of the second movie)
-load first file of first movie,append second file,select the ac3 from the step above as secondary stream in nandub
-audio/video to direct stream copy,save avi (you can also split it in this step)
finish
