I transferred several QT .mov files from a colleague's Macbook Pro in order to edit them in Final Cut, but I am unable to view the files. I hear the audio, but can only see a black screen. I have a Macbook with the same configuration as my colleague (2.4 GHz Intel Core 2 Duo), and we both have Quicktime 7.6.2, so we're both baffled as to why the footage plays on his laptop and not mine. At one point I received an error message ("Additional software is required for Quicktime to playback this media. It may be available from the Quicktime Components page." This takes me to a Quicktime page with a bunch of plug-ins, but there is no indication which, if any, of these I need to install. I've visited a bunch of online discussions about this topic, but they all indicate I need some sort of codec. Most of the discussions say DivX will do it, but after installing it, I still experience the same problem. Any advice will be greatly appreciated!
