Sorry, I couldn't reply till now, just got home.
Capture device is a Sony DSR-30, pretty nice deck.
I haven't dumped my preferences or repaired permission yet. I'll try it, but it dosn't seem like that would be it being that I've only had the system for about a month (not much time to screw up any preferences).
After closer investigation, I no longer think that the freezing is directly related to capturing, it's just slow - with a lot of tasks. I did find some things on the faq that I can try with that though.
I just tried capturing a little while ago and when it hit a time code break it didn't freeze, it just started rewinding. I expected this to happen, fairly normal. I can just log around the TC breaks.
Thanks for all the replies thus far. I'll try some of the suggestions on the faq to see if I can get my system running a bit faster.
