What juhiatti wrote may be possible, but probably not using the AVI file as audio.

Consider how a SVCD or VCD works on the PC...

The filesystem points to "DAT" files... However the "DAT" files are no more than the mpeg data written as separate tracks in mode2 form2 (i.e., 2324 bytes per sector as opposed to standard mode1 or mode2 form1's 2048 bytes per sector). However, these can already be read as normal files on most PCs.

Presumably, someone could create a tool to author a disc with a similar physical and logical layout as a VCD. That is, the first track has the ISO filesystem and from there it points to data written in mode2 form2 on subsequent tracks.

Regards.
