my problem is as follows:

i have a MPEG-File of a Movie.

i have TWO WAVE/MP3 Files of the Audio for the Movie.
one is in English,one is in German.

i want them BOTH on the MPEG File.

well,WAVELAB tells me the files are too big to be combined,even if i use only one Channel of each.
(both are plain Mono)

What i want is ONLY a VCD with LEFT CHANNEL - ENGLISH and
RIGHT CHANNEL - GERMAN.

as i cannot combine WAVE-Files into one - is this possible with MP3 Files????? and IF YES - WHAT PROGRAM do i need????

any Help very appreciated!

You might have more luck if you ask on a site which is more oriented toward movie ripping/encoding. Try Doom9, for example - http://www.doom9.org/

You can do it with WAV. Downmix your wavs to mono, then combine them in a WAV editing program.
Can do it with mp3 too in an mp3 editor...... All you need is a good WAV editing program.

I think creative WAV studio might do it.
