The output from the cable box is an MPEG-TS stream over firewire. Playback
works fine for 720p channels. The clip I am testing with was captured off
of PBS.
I've tried playing the clip back at half size with VLC, and the results were
the same. I'm having trouble figuring out how to do any scaling with
mplayer.
The GPU is an old nVidia GeForce2 card w/ 32MB of ram. I don't know much
more than that.
Here is the current state of my xorg.conf (I switched to the xv driver
earlier this evening, disregard the monitor section as that is not actually
my monitor):
# Xorg configuration created by system-config-display
Section "ServerLayout"
Identifier "single head configuration"
Screen 0 "Screen0" 0 0
InputDevice "Mouse0" "CorePointer"
InputDevice "Keyboard0" "CoreKeyboard"

Section "Files"
# RgbPath is the location of the RGB database. Note, this is the name of
the
# file minus the extension (like ".txt" or ".db"). There is normally
# no need to change the default.
# Multiple FontPath entries are allowed (they are concatenated together)
# By default, Red Hat 6.0 and later now use a font server independent of
# the X server to render fonts.
RgbPath "/usr/X11R6/lib/X11/rgb"
ModulePath "/usr/X11R6/lib/modules/extensions/nvidia"
ModulePath "/usr/X11R6/lib/modules/extensions"
ModulePath "/usr/X11R6/lib/modules"

# Specify which keyboard LEDs can be user-controlled (eg, with xset(1))
# Option "Xleds" "1 2 3"
# To disable the XKEYBOARD extension, uncomment XkbDisable.
# Option "XkbDisable"
# To customise the XKB settings to suit your keyboard, modify the
# lines below (which are the defaults). For example, for a non-U.S.
# keyboard, you will probably want to use:
# Option "XkbModel" "pc102"
# If you have a US Microsoft Natural keyboard, you can use:
# Option "XkbModel" "microsoft"
#
# Then to change the language, change the Layout setting.
# For example, a german layout can be obtained with:
# Option "XkbLayout" "de"
# or:
# Option "XkbLayout" "de"
# Option "XkbVariant" "nodeadkeys"
#
# If you'd like to switch the positions of your capslock and
# control keys, use:
# Option "XkbOptions" "ctrl:swapcaps"
# Or if you just want both to be control, use:
# Option "XkbOptions" "ctrl:nocaps"
