When I use POV-Ray to render an animation into a QuickTime file, the movie
comes out just fine and I can play it in QuickTime Player with no problems.
BUT - if I then scp the file to my website and download it in Safari, I
get an error message from QuickTime - "Could not open the file ... because
it is not a file that QuickTime understands." This happens even if I scp
the file back to my Mac. In fact, I can take a working .mov rendered by
POV-Ray, scp it to another machine, scp it back, and run diff to verify
that the files are completely identical - and yet the downloaded version
won't work with QuickTime. How is this possible? What's going on?

POV-Ray is not meant to create QuickTime files for web display directly. It
is meant to create QuickTime movie files for easy post-processing. The
QuickTime movie output is only useful if you export with a high-quality
codec and then compress the files for web streaming later on.

Use the QuickTime Player File menu Export option. Please read the QuickTime
documentation how to create web-ready QuickTime movie files.

I thought of that too, but QT Player 6.5.1 doesn't have an Export command.
I was able to get a working print by feeding my movie through iMovie, but
the results weren't very satisfactory; it dropped every second frame,
regardless of the codec I used.

Ah, forgot, you need QuickTime Pro for that. It is a good idea to have
(unless you have some other movie editor - iMovie is for editing digitized
video) if you want to publish video on the web to have a tool to compress
movies for optimal playback online. POV-Ray can only store one frame after
the other, and it has to close and reopen the movie after every frame in
order to allow recovery in case you abort a render. As such, movies created
by POV-Ray will never be efficiently compressed anyway - that is also why
you should select a lossless (i.e. PNG) or not very lossy compressor (Motion
JPEG with low compression) when selecting QuickTime movie output in POV-Ray.
You can then feed that movie to a program to do a final and very effective
compression using a compression method much more suitable for web use (in
particular MPEG-4 or Sorensen).
If you have Classic, you could try to use the older MooVer to do this. It
will allow you to compose single frames POV-Ray will render if you select
any other output file format; and MooVer will turn them into a movie:
