Hey Greg. IÂ´m in the middle of a similar strange problem - trying to import an mpeg I made into Premiere for editing...it accepts it but handles it "a bit slowly": 36 hours for 70mb...!
So, I tried converting to avi with WinAVI - the result was a 7mb avi file which Premiere wouldnÂ´t recognise!
How weird is that?
You say Quicktime can convert it? I havenÂ´t checked it out - think itÂ´s worth a try?
By the way - browsing thru the forums - ran across the first post in this thread, while half watching a video on my tv - looked back and saw this (screenshot below)...scared the hell out of me...even tried to click the ok button! Good grief @ haveacigar - nice resolution!
