Recently upgraded to 360 and have one problem we can't solve.
Both boxes are set to fast start, and both set to wait 24 hours before going into standby.
Both boxes seem to go to sleep if left for a few hours (eg between breakfast and lunch), the light on the front stays white, but the screen is blank and no sound. No button on either remote will wake the box, and I have to use the power switch to reset it. I then have to wait for the reset screens etc. We're currently avoiding this by manually putting the box into standby, but my mum sometimes forgets and then if I'm not home to reset the box she can't turn it back on again. How can I avoid this?
