I´ve been using startonwake to avoid this problem and in the beginning it seems to helped, but lately i notest that even with this method on wakeup i have some Blue Screen probs and no TV signal
I think i would be very concerned about the BSOD, they usually do point to a hardware\driver problem, which may not show up until some software put's a strain on it.
How about TVE3 with the NEW powerscheduler client plugin, am actually having some success with that.
For a reliable HTPC it must successfully turn on\off for recording and PVRScheduler does this very well for me.
