There are two types of WC4 DVD.
First one was bundled with Creative Labs DVD 1x-5x kits. Double-sided, and required the hardware video decoder card that came with the DVD kit to play the movies. This version has theater-quality video and sound, as well as the various Win95 version features (Direct[Sound/Input/etc] support being the biggest feature).
The other one is a special OEM deal that's just the Win95 version of WC4 put onto one double-density single-side DVD, with the non-data side having the same basic design as the regular CD version (yellow-orange background, Black Lance triangle in the middle). It has the same video and sound quality of the original DOS version release, but with the ability to eliminate the black lines breaking up the image with a command line option in the shortcut (just stretches the image to fill in the blanks, though, so the non-interlaced video looks kinda ugly, IMO), as well as Direct[stuff] support.
Either version will work with any DVD drive, but as noted above, with the first version you can only see the movies with the hardware decoder card installed.
