I have to use a particular file from an FTP site a few times a year and this year something happened. It is a .mov file but when I go to play it it is just a musical note and a back ground and there is no audio. The time slider plays at normal speed and nothing happens. I tried another file and the same thing. I contacted the company and they say it plays fine on their system and it might have something to do with an avid .mov codec. I have FCP7 and everything is updated via the system update and it says I have no other updates. Any suggestions? BTW the company won't send a different file since it is my problem I can't view the file.

You could try some avid codecs for quicktime, like this one:
Avid Codecs / DNxHD 2.3.7 - VideoHelp.com Downloads (http://www.videohelp.com/tools/Avid-DNxHD)

Maybe google "avid codec quicktime" and see if anything works.

Hey Jordan. That worked perfectly. It is amazing how many times you can google something and can never find it and a quick post on here and you have your answer. Thanks for your help
