Sure, why not. A laptop is just a computer in another form factor.
Laptops tend to be slower, and have less storage, than desktop PCs, so you
will need a fast machine, with sufficient storage (or available network
storage). Laptop video hardware tends to be more lightweight, so VDPAU is out
of the question except in rare cases.
HD will be more of a challenge for the hardware, especially on playback. Note
that "HDHR" does not mean "HD", as a lot of SD material is transmitted
digitally. "Digital" does not mean "High Definition", in spite of confusing
You might also be able to use USB type tuners, like the Plextor PX-TV-402U and
some recent Hauppauge units, as well as the HDHR. I suspect that few laptops
would be able to play back the h264 that the HD-PVR produces, except perhaps
at very low bitrates.
Make sure you have a laptop with a hardwire (RJ-45) network port, using WiFi
for video can be problematic.
So, while not the best choice, a high-end laptop should work. Most people who
use laptops with Myth use them as frontends only.
Most backends run 24/7, unless you have set up some wakeup method, again,
possibly a problem with laptops. If you do run a laptop 24/7 make sure it has
plenty of airflow for cooling.
Laptops present several challenges for Myth systems. You might want to try and
gain some experience with Myth on desktop hardware before attempting to use a
