Ahh that makes sense. That also explains why I couldn't use dd to cut a 
.MOV file in half and play the first half!

I was thinking about that. I know that at one point I modified my 
converter script to read from pipes, and I know it worked, but I've been 
thinking that I must have only tested it on other movie file types and 
probably didn't actually test it on a MOV file.

Thank you all very much!
