Beta seemed a lot more... easy-going. And stable.
I've experienced 2 lock-ups as well. For some reason when an .avi reaches the end and playback stops, system stops as well.
Pushing ctrl+alt+del gives black screen as it tries to load the log-on screen with options, but it never gets there. So weird, HD led keeps blinking indicating activity, mouse cursor keeps moving, no crash or error... it just stops responding.
I have a RAID array as well, and the page-file is on it, entirely (no portion on c: drive). Maybe the array goes to sleep due too inactivety during playback (playback is from second partition on primary disk). Will have to play around with the power options and page-file.
