GuiltyGearX-the strangest problem

[GarbageWater]

Ok, I have a bunch of copied dc games, and I've been able to burn them all using discjuggler. However, two of the games (Guilty Gear X and Vampire Chronicle) are seemingly impossible- the computer keeps on registering the cd as an audio cd. I have actually played these games on my dc so I know that's not true, but incredibly enough, these cds actually can be played as audio cds on a regular cd player. When I try to burn these games, I end up with an audio cd but not playable on my dc. Has ANYONE ever encountered this problem, and if so, can you tell me which program I can use in order to make a proper copy?
