I have just installed a TBS6284 PCI-E card in my Windows 7 PC.
Fitting the card and installing the drivers from the CD (version 1.0.0.2) proceeded without problem. I then started Windows Media Center and configured the 4 tuners for use in Media Center. The channel scan returned all of the channels that I expected. (Note: currently only DVB-T channels can be received at my location; DVB-T2 channels do not arrive until next week!) I then tested the installation by making 4 simultaneous recordings in Media Center. This too was successful. I then put the PC into sleep mode (power state "S3").
The problem arose when I woke the PC from sleep. I went to the Windows "Device Manager" panel and looked for the entry for the TBS6284, but it was missing. I then tried to view live TV in Media Center but this failed, saying that there was no tuner available.
I rebooted (which caused the TBS6284 to re-appear), went to the "Details" tab of the TBS6284 properties in "Device Manager", and looked at the "Power data" properties. It claims that power state "S3" maps to "D3", and that power state "D3" is supported. It also claims that wake from power states "D0", "D1", and "D2" are supported, but significantly it does not state that wake from power state "D3" is supported. As a comparison, I looked at the equivalent data for a Pinnacle 2000i DVB-T dual tuner that I also have installed in the PC, and that does state that wake from power state "D3" is supported.
I am no expert in Windows power states, but is this lack of support for wake from power state "D3" an error in the TBS6284 .INF file, or does the hardware really not support wake from "D3"? Or is this a capability that is not yet supported by the driver? Or are there some other settings that I need to set? Help please!
