Dont confuse yourself by thinking of the check as either CD or DVD. It is simply a MEDIA check. e.g. If its on CDR it is 01 and if DVD it is 02 (they are not the correct values, its been a while since ive had to manually patch a game)
Part of the ripping process originally was patching them for CD.
Make sure that part of the process in making the multigame dvd is to patch the games (generally rips) back to DVD.
Even original CD based games have the same check and need to be patched to DVD if you want them to work as a multigame dvd.
These days i use v3.5 of Sonix DVDScan - you can patch between cd & dvd at your leisure.
Hope this was of some help and i havnt confused you more.
