[mythtv-users] Remote to turn *on* mythtv?

[Chris Weiland]

Just out of curiosity, which board do you have, and do you know if it's
possible with your board to do suspend-to-disk with usb wakeup?  I've been
wanting to do this too, but I didn't think it was possible.  I have an Asus
M2NPV-VM, which seems pretty fully featured, so hopefully it will work.
