Re: Video playback becomes slow and jerky.
I have PT 10 HD on a Mac Pro 8 core 2.66 Ghz machine. I am using 3 monitors, one for video only.
I have found that converting my videos, (which are 50 minutes long) to DV was a waste of time, and actually degraded the quality, so I leave them as .mov files now.
Sounds like you are doing everything right. There is a preference for setting the quality of quicktime video playback...you might take a look there. Is your frame rate correct? Can your video card support your playback? Are there any other apps running, like time machine, etc, that kick in on a certain schedule? When you set your processor at 99%, if the computer even turns it's head and coughs, it may interfere with ProTools. That's why they recommend turning off Bluetooth, Screensavers, avoid spinning the hard drives down and all that stuff.
Hope that helps....
