it still doesn't work. I was VERY careful this time to follow the proper static discharge precautions and I have done this a few times so I'm sure that I have the connector on the card seated properly in the mezzanine slot. I keep geting an error message saying the "Pro TV in use by another application" when I try to get a new video display. The edit, setup and record pull down menus are also greyed out. I tried reinstalling the application software after I installed the card, but it is acting just like the last one. The only indication I have that the card is properly installed is the clock in the tuner window shows the correct time. I just tried starting up from both orange CD's that came with the computer, and I tried resetting the PRAM. Neither of those worked. I'll try a software restore tomorrow if my wife gets her documents backed up. Will this reset any firmware or ROM updates that I have installed since getting the computer? Once again, I have a revision B iMac that has been refurbished by Apple. If you have the iProRaid-TV card, please check to see if you have a refurbished unit. It will be on the box or maybe in any printed documentation you got with your computer. Thanks for everybody's help.
