[Mp4-tech] Can Common Players Play MPG, DAT or VOB File with MPEG4 Video & G.72X Streams ?

[swhong cs.hku.hk]

Dear all,
After finding that there is no familiar/common multimedia players under 
Windows can playback mp4 file with MPEG4 video stream and G.72X audio stream. 
Then, I tried to check whether MPG, DAT and VOB file formats can or cannot 
fullfil my requirement. I understand that all these formats support multiple 
and application/user specific streams. However, I cannot find any multimedia 
players that claim to support the playback of the mentioned multimedia streams 
at the same time so far. 
Does anybody know that whether the MPG, DAT or VOB format with MPEG4 video 
stream and G.72X audio stream can be playbacked on Realplayer, Windows 
Mediaplayer, Winamp, etc. ? 
Actually, I am thinking of using AVI format as the container for the MPEG4 
video stream and G.72X, but I have a question that can AVI embeds multi-
audio/video streams and proprietary (i.e. application specific) data streams 
simultaneously ?
Please advise, thanks in advance.
