Ah Ha, caught you. Anybody running a 7800 is more than an
Just my opinion, but a Myth system really needs to run full-time if
it is to be a true full-time replacement for all of your
entertainment gear. Otherwise you have to watch your recording
schedule and be certain that the system is up when it needs to be.
You can even run a "wake from sleep" schedule but I'm not aware of
any "Wake from the Dead" capability, and if your box is running
Windows it might as well be dead.
I play the occasional game as well, but on a Linux machine (not my
Myth box). The 6800 in it works pretty well, but I admit I'd like to
see what a 7800 would do, now that AGP versions are available.
I run Windows on the Linux machine under QEMU and it runs pretty
well, but the Cirrus Logic CLGD 5446 PCI card that it emulates pretty
much precludes any games :-)

You were very lucky, both in your cable operator's choice of
equipment and the fact so many channels are available that way. Be
aware that it could change any day though.
