I have a Dell XPS420 HTPC which has a problem with my TBS6284 quad tuner card (it is absent from "Device Manager" on wake from sleep). I believe that this is caused by defective motherboard BIOS (Dell did not implement PCI-Express version 1.0a correctly). So I cannot use sleep with this system.
But I can use hibernation with this system. I think that hibernation re-initialises the tuners on wake, and this avoids the sleep problem. However, hibernation has usability difficulties (as distinct from the functional difficulties that you are currently experiencing). In particular:
(1) You should disable the POWER button on your remote control (if instead you change it to hibernation, it will terminate immediately any recording that is in progress when you press the POWER button).
(2) You need to wake the HTPC by pressing the power button on the system unit; you cannot use the remote control to wake the HTPC.
There are solutions to both (1) and (2), but you should first try hibernation for a few days to see if it will actually solve your problem (your problem may be different from mine, and not susceptible to the same solution).
