I don't know if it's even remotely helpful (and apologies as this reply is stuffed with non-ASCII characters), but if I fetch your video over a raw connection I see:

It looks like some encoding or serving issue (not least excepting the "junk data" stuff in your header), but the presence of lots of @^ reminds me of UTF-8 encoding, whereas an AVI should probably be raw bytes.
Not really an answer, but it may give a clue :-)

Unfortunately your message was sat on by the ALUG mail server and only arrived this morning -- 5 days later! Sent at 06-Jan-10 23:43:35, it now predates the revised version of the file which I uploaded at 07-Jan-2010 18:29, and this one works:
http://www.zen89632.zen.co.uk/DenverMill/denvermilllookeast2010.01.05.avi
Inspecting my local copy (of the revised version, which works), I find similar sequences of "00" ("^@") bytes, and of "[= MPlayer junk data! =]".
Your comments got me googling for "MPlayer junk data". This seems have raised queries on many occasions, and the general response from those who seem to know what they're talking about is that this is just mplayer filling-in unused space in the header block (presumably of fixed size). I didn't see and comments about "00" bytes, but quite possibly these are similar unused space.
See, for instance,the reply by Joe Forster/STA to Cyber Akuma on http://fileforums.com/archive/index.php/t-77955.html (about halfway down the page, dated 20-08-2006, 02:27).
The fact that the revised version now plays perfectly well on Linux and in Windows (as confirmed by some people I pointed to the file) indicates that the original problem has nothing to do with these features.
It may amuse people to read a comment in the reply from one:
"initially it said the file was corrupt but after saving it to the desktop it played just fine. I have had that issue with other files so it's not just yours. Probably a Windoze problem as usual."
Thanks again, and best wishes to all, Ted.
