It is my understanding that (S)VCDs have MPEG Program Streams in Mode 2 
tracks, instead of using Mode 1 like ISO9660. This allows more space for 
the movie, since it doesn't have all of the Error Correction Codes 
(ECC). Therefore, VCD movies aren't readable from an ISO9660 
filesystems, though the disc typically has a small filesystem for 
miscellaneous extra stuff. I suspect (though I'm not certain) that if an 
MPEG movie is readable from an ISO9660 filesytem, it isn't really a VCD, 
but an MPEG movie on a CD-ROM.

There is a Linux filesystem driver that can expose CD tracks as files, 
so reading the correct file should render the MPEG stream.
