Excellent! However, there is one quirk of Media Center that it is worth knowing.
When MC is recording, playing live TV, or playing recorded TV, MC turns on a flag that prevents sleep or hibernation (this is what you want). MC turns off this flag when not recording, and when not playing live TV or recorded TV. But MC also turns off this flag when live TV or recorded TV is paused
Consequently, if (say) you pause live TV and go and make a cup of coffee, and it takes longer than your sleep timeout, MC will sleep the system, and you will lose the contents of the live TV buffer. Similarly for pausing playback of recorded TV -- MC will sleep the system after the sleep timeout has expired (but you don't lose the recorded content, obviously).
I found that 10 minutes sleep timeout was too short for my use of MC; far too often I would come back to the HTPC to find that it had gone to sleep. If you use a much longer sleep timeout (30 minutes, say), this irritation is less likely to occur. The cost though is that the HTPC will run for up to 30 minutes after a recording has ended before the system sleeps (precisely what happens depends on the circumstances, which is why it is "up to 30 minutes", rather than "exactly 30 minutes"). So the choice of sleep timeout is a compromise between these two effects.
