Next you have to figure out what to look for and where. There are plenty of places on the net to get these-you already have QT and AppleVideoPlayer (comes with every OS install). My guess is you will only be able to find the latter (sorry Mac fans ). The former AFAIK just includes Query's NetviewDisc player, the latter includes Quicktime itself, Apple VideoPlayer, MacVCD, VCDPlayer, BetterPlayer(?), and others. You got 2 kinds of apps-those that see a VCD in 'Disc' mode and operate on the PBC info as well as the MPEG tracks, and those that see a VCD in 'File' mode and just operate with the MPEG tracks. OS9 shouldn't have any problem with the ISO9660Mode2Forms1and2 and MPEG1Mode2Form2 tracks, so that narrows down your problem to apps that recognize the type of file/track.
There are good things (more apps and app possibilities) and bad things (unavailable Filesys drivers) about being on OSX, but since he SAID he was using OS9 and not, it is more helpful to refer to solutions that work with that OS.
You guys need to listen more closely to what the man said.
