XP bluray disk contents problem

Hi,

Thanks in advance for any help. I have just bought a TDK TBU150 Bluray drive the external 1. The drive is recognized in both Win XP SP3 & Win7 machines I have. Win7 works all right and plays no probs with power DVD10 it came with. Problem is XP will not recognize any bluray disks (seen in windows explorer), DVD's OK, CD mp3 etc OK. Do I need a special "driver" in order for XP to see the the bluray contents or is it something else?

Regards

Hartless
