Missing Frames when I import from HD Connect MI

I recently purchased the HD Connect MI for a 30 sec commercial project that was shot with the Sony Z1U at 1080i60 in HDV. I edited the video offline in HDV and then went to do an online out of my Sony M25U deck, through the Connect MI and into my computer via my DeckLink HD Pro Single Link Blackmagic card. However,I am having some issues regarding choppy footage. I tried importing using 1080i60 uncompressed, which was extremely choppy, and when I went frame by frame in the quicktime file it was missing frames. I then tried importing the footage using the Apple Pro Res with better results, but still a few frames missing. I have a dual processor G5 with 4GB of RAM and am digitizing to my Lacie Biggest S2S raid. Is it a speed problem that is not allowing me to import uncompressed? Do I need more RAM? My RAID doesnt have that much space on it. Do I need to import to an empty RAID? Are there some settings I might be missing either on my deck, my blackmagic card or on Final Cut? Thank you Creative Cows- I love the website and read it every day. This is the first time I have posted anything.

The speed of your processor / disk I/O system is clearly the problem. I would try a clean disk and see if the dropped frames problem is reduced or eliminated, as the disk I/O speed drops as the disk fills up (and data is written to the slower parts of the drive). 4GB is plenty of RAM.
Also, I don't think ProRes works well on the G5. Check the Apple website, but I think you need one of the new Intel-based processor systems for good ProRes performance.
