I am having a problems with my decklink HD single. I have been using a JVC monitor (no deck yet) and a Dual 2.5Ghz powermac G5 with 6 gb ram. The problem started with the monitor image not loading up or sometimes the image would shut off. Recently it only gave me light snow. I tried to move it to the top 133Mhz PCI slot to no avail. I then installed/unistalled/reinstalled the 5.6.2 and 5.7 drivers. The closest I came to getting it to work was when I had just downgraded to 5.6.2 from 5.7. After restart the destop appeared for 15 sec before returning to black. It was heartbreaking.

This is what my system profiler reads:
pci-bridge:
Type: pci
Bus: PCI
Slot: SLOT-4
Vendor ID: 0x3388
Device ID: 0xa104
Revision ID: 0x0000

Any ideas?
