Hi Paul,

This doesn't directly relate to your situation, but we were having similar issues with our PC ultrascope box. From the day the system arrived it had similar playback issues to what you've been experiencing - 2-3 second lag with picture and steppy playback far from realtime (like 5 fps).

After a lot of back and forth with the local distributors the problem was isolated down to the latest graphics drivers that the system came with. The 4650 card was running 11.x drivers. We completely uninstalled these and reinstalled v10.2 drivers and the machine now works perfectly.

Not sure if that relates to your situation with a Mac but it could be worth a shot. Call your distributor to confirm which version of drivers the card is supposed to work with.
