Argh - tons of clips to watch but they are mov files. Since I am not keen on downloading QuickTime as the darn thing takes over your files I am looking at an alternative - http://www.free-codecs.com/download/QuickTime_Alternative.htm
This works well if you guys want to try it out.
I presume you are using a digital camera not a camcorder. We bought a new Canon stills camera the other day but though it does movies it has no sound! Argh!
Mine makes avi files. I have uploaded one in the Off-Topic section under my 'sans avions' thread.
