In Premiere Pro 1.5, I drop any .MOV on the timeline. When I play it back it shows about 1 frame for every 10. The sound is ok. When I inspect the file properties it shows 2.99 fps rather than 29.97 like it should.
Also, I get the same choppy behavior in the quicktime player. The file does play ok on 1) other windows computers (quicktime) and 2) through a freeware player called VLC on the "problem" computer.
I have reinstalled quicktime. version is 7.3.1
