OK, now I understand. Thanks for that explanation.

Interestingly, I tried using VLC on a different windows client than I
tried previously. In this case, the .asx container hands off the
download just as you describe. One major difference is that this client
was direct attached to the same 100 mbps network segment as the
mythbackend. Previously when I tried, it was a windows client that was
attached via a VPN that has a max uplink of about 640 kbps. Maybe that
is why I experienced the file errors?
What I want to achieve is to watch a compressed stream from my Myth box
while at work. The embedded flash player in mythweb works. I was just
hoping to find a way to open the same stream in VLC (or another player)
that could be resized for 16:9 content and have the window about 2x
larger than the embedded window. Seems that if this is possible, I'll
find my answers with various ffmpeg incantations and it will be a manual
process for me, since I'm not much of a PHP/Perl coder. I'll probably
just settle for the embedded player. :)
I've also found that VLC will "stream" a file that's being downloaded.
In other words, if I click the download link in mythweb and save to my
hard drive, I can then open the file from my hard drive in VLC and begin
watching before the download has completed. Also by watching in this
manner, I can skip forward and back (up to the limits of what's been
downloaded) and thus skip commercials.
Thanks for the input and sorry I've been away from the thread for the
past few days.
