I've been trolling the forums (and MS support) for a solution to this, but I haven't found anything yet. I have an HTPC (HP s3300) running Vista Home Premium, and I can't seem to make it go back to sleep automatically after it wakes up to record programs. Instead, I manually have to press the power button on my MC remote when I get home from work (usually several hours after it's finished recording). What baffles me is that when I change the power options to have the PC automatically sleep after a specified period of time, it will NEVER sleep...even when I press the power button on the remote. Any suggestions?
