Thanks. I was able to download and access the first QT (73.7 MByte,  
using the Techsmith Screen Capture, Integer (Little Endian)) version.  
However, I have both Flip4mac and the Perian toolkit of codecs that  
extend Quicktime on my mac.

I have never heard of the Techsmith codec before. The other two files  
have codecs I do recognize, but not the "integer" or "Little Endian"  
specification.

The file size is directly related to the bitrate, which is not  
surprising.

The upshot is this: I am a poor tester for video compatibility on  
'stock' macs because I have extra (free) codecs that others may not,

and

video is still a quagmire. I make my videos with straight H.264  
encoding (and AAC for audio), and that seems to work more universally,  
plus I have control over bitrate, etc. at the time I do the encoding.  
For videos like this, I use the same tools that David Reiss does (on  
macs), and there have been no problems with my windows-using friends.
