I dont want to jinx myself but i am working on a 2.3TB HD movie project. I use PQ tapes all the time. ONe thing about capture using Canon is that Canon does not like it when you have other firewire or external Hard drives connected to your computer when capturing. So and again you may already do this, is to make sure you have 125 GB of free HD space on your computer- capture via firewire, then once done then you can transfer footage to external HD. But again nothing else should be plugged into the computer until after full capture. If your camcorder is recording without dropout then it should be able to capture onto your computer. Now if you see dropouts on the camcorder playback then its tapes, and again Panny PQ are really good--63 minutes. I would not recommend 83 minute tape as the canon's seem to have timeline trouble with playback. Also if you can as you are capturing to your computer make your screen size as small as i can go so as to make sure the processor is not working over time. Again Canon does not capture well to a computer unless you have at least 125 gb of free space, ( capture one tape at a time 63 min tape) make sure no other device is connected to your computer except the camcorder. Then once finished with capture connect external HD 7200rpm HD and transfer the capture off of your computer, then you are ready to capture via computer again.
