I'm having some problems with 5D MkII footage. When I drop them into Compressor it crashes. On one machine I get the pinwheel for about 15 seconds, then it crashes and on another I just get the pinwheel until I have to force quit. It seems to be working fine in MPEG Streamclip so I have a workaround but I'd like to figure out why Compressor isn't working both out of curiosity and eliminating the problem for the future. Thanks!
