I agree with the above guy. If you do not mix and match resoulutions you will have less problems with premiere. I can tell you one thing I have used 5.1 and now 6 and have never crashed it once. What os are you running I run NT and 2000 with no porblems. If you use win98 expect crashes. They should have called 98 CRASH!!(posted 8385 days ago)Just My 2 cents
