playing ac3 as second language

[mironto]

hi,

well, I have video with one language mp3 audio and other language is in ac3 5.1. I wanted to insert mp3 into video and ac3 leave as second language on separate cd (to keep better quality in video). but when I play such a movie in microdvd (and other players I tried) and switch to secondary audio, the sound is choppy (this also happens when I play only the audio file).
can ac3 be played only inserted in video (to keep sync)?

any help would be appreciated

all right, because nobody replied with any idea, I had to come up with something myself...
The solution is I made video 16x16 pixels with black picture and put ac3 track into it! So the video is 3 hours long with black picture and ac3 sound which is playing exactly as it should (the video compressed to about 10MB for 2:45 movie, maybe I could push it lower, but I didn't need to). Now when I play primary video and put this video as secondary language, the result is great

if you have any comments, I'd be glad to read them.
