Hi Sandra,
we had the same trouble with P2 files which were imported to avid. we bought the mxf4qt product from mxf4mac and it saved our life. we also tried raylight but it doesn’t help if you only have the pure mxfs. we tried the p2cms and calibrated but there is not timecode and it is very slow. the fcp project took 10 minutes to open. we tried mxf4qt and there is timecode and it works with fcp very fast. we received a beta of p2 flow from mxf4mac and this one is just fantastic if you work with the unchanged p2 contents.
the web adress is mxf4mac.com and I found a movie at you tube youtube.com/user/MXF4mac
cheers
michael
