The only way I can concieve of this happening is to run the video app as a
local app. It is not possible to pass uncompressed high resolution video
over a 100Mbit network, which is what happens when you try to do this on a
standard LTSP set up with remote apps. Running as a local app the video
would be passed compressed, and then uncompressed on the client.

that is NOT true.
I watch mythtv 3 times at once. One on the console, two on fat clients on a
100M network. HDTV is 15Mbit/S so there is plenty of spare, and watching it
is good viewing. The processor/graphics card is more relevant than the
network. I watch SDTV (16:9) cause myth does not do HD too well, although
network vs console are indistinguishable.

Uhm, wow. comparing bandwidth usage of a terminal watching video and on
a local machine is quite different.
decoding it locally (what you're doing and what he said would have to
happen)takes whatever the bitrate is plus, say, 10% for errors and
protocol, and crap.
Decoding it at the server(LTSP) takes roughly XRES * YRES * COLOUR_DEPTH
* FPS, so playing a 24-bit, 25fps movie @ 320x240 would be 320 * 240 *
24 * 25 bps(which I think is close to US TV resolution), or
46,080,000bps, or roughly 50Mbit. Getting XDamage will help that a bit,
and turning on X compression would help too.
