I think you really should check out the link I provided since I am no where near an expert on vcd.
I know WMP 6.4 plays it tho'
here is something I got off that site that might help you:
In order to play VideoCD's on a PC (or even copy the dat files from a VideoCD in the CDROM drive to the PC's disk) you have to have the virtual device driver SCSI1HLP.VXD in Window's \SYSTEM\IOSUBSYS directory; otherwise, the file structure will not be recognized by Windows. My file was there but some program had changed it's extension. After renaming and rebooting, my VideoCD's now run without a hitch.
Again, check it out...there's tons of info on that site.
good luck.
