I get a "blank white screen" in LiveTV under Windows Media Center 2005

I get a "blank white screen" sometimes when I attempt to watch LiveTV under Windows Media Center 2005. This happens intermittently ... and tends to "go away" if I reboot. The issue is that I have not yet figured out what is causing it, and don't want to simply accept that rebooting my computer will always fix this (I am not sure that it will).

My computer is a Windows XP Media Center Edition 2005 machine with a ATI Radeon 4670 with the latest Catalyst drivers (9.3) , a Hauppauge WinTV HVR-1600 tuner also with the latest drivers, running on a 28" Hanns-G monitor via HDMI.

I believe I have figured this out.

There is a tool "Windows XP Video Decoder Checkup Utility" that allows you to specify the default codec used by WMP and MCE (by extension) to play video. By using this tool to change the codec being used by MCE's LiveTV to the one installed by CyberLink Power DVD, I now get decoded video when I start LiveTV (and not the White Screen with audio I was before).

Can you check the cable source, is it splitted to be used with other receiver or TV.
