I asked sub at GBPVR whether the new ATI drivers will support use of GBPVR. Confirming SHSPVR's findings, sub posted the following:
"To be quite honest, I'm becoming disillussioned with 550 Pro, which is unfortunate considering it sounded so good on paper.
I tried these new drivers, but still no audio out of PowerCinema, Microsoft AMCap or GB-PVR. I'm fairly sure they've either sent me a lemon, or it has a PAL I tuner, or the device is in some way not compatible with our PAL B/G here in New Zealand.
Within 48 hours of PowerCinema (or any other application) producing successful audio/video on my machine, I'll release a version of GB-PVR which works with this device. Until then, there isn't really anything I can do." http://forums.gbpvr.com/showthread.php?t=4865
Until something changes, we remain stuck with Cyberlink.
Ironically, I received a survey today from Cyberlink about the Power Cinema software I downloaded awaiting the CD from Sapphire. I let them have it with both barrels, pointing out most of the deficiencies posted above. I am not holding my breath.
