AJA IO LD compatibility with iMac 20 2.0 gig processor
Guys, someone told me the AJA IO LD would not work with an iMac, I read nothing of this in their literature . . . . Is this True? THANKS!

Well, it would work, but how are you going to capture your media? In order to capture uncompressed video (which is the reason you need to io) you need relatively fast drives, such as a raided firewire 800 disk from lacie or medea. Once you plug in the io ld into your g5 imac, all of your firewire bandwidth is taken up and the g5 has no way to expand. You are better off using a powerbook as you can put another firewire bus in there with a cardbus card. AJA has a few words to say about this configuration and you can read about it here:

Sorry to say, but this would be a problematic setup. You really need a G5 tower.
To capture uncompressed video, you need a separate RAID array (speedy drives) or a FireWire 800 RAID. You cannot add either array to an iMac that offers no FW800 ports or PCI slots for a RAID array.

I only want to edit DV resolution. This system can handle that can’t it? I do it all the time on my laptop. This is strictly going to be used for DV. Need the control of the IO for Dbeta, Beta and DV-SDI . . . . . That will work, right?

Sounds like a neat idea but everybody is correct. When you use the firewire port for the IO LD, you have essentally used up the firewire bus bandwidth. And obvisiously, you wish to record more than just DV if you want an IO LD. If so, then you might want to consider trading your iMac for a G5 tower. That way you can upgrade the system by adding an additional firewire card to control the IO LD only.
And one more thing, if you digitize to you internal drive with what you are wanting to use, you’ll get dropped frames and screen grabs. An internal drive that has you MacOS cannot handle running it and trying to run DBeta or any SDI signal other than low quality DV, such as home movies done with a consumer based camcorder. That’s another reason for the G5. You can add SATA drives for hardly anything and edit DV quality just fine and possibly DBeta recorded using the DVCPRO50 codec. I do this using two SATA drives raided together on a G4 dual 1 gig.
So to answer your question. It would not be wise to try it on an iMac. You need banwidth and expandibility.
