Have exactly the same problem, besides a few other Vista specific
annoying problems.
From day one, after upgrade from pre-installed XPSP2 on my Scaleo C2DUO 6800
after every cold-boot, the Realtech Audio driver is reinstalled. Few day ago
i installed a Hauuppauge PVR 150 MCE, Vista didnt ask for driver, but
installed it by itsself. After setting the channels for radio and tv it
worked fine. However next day after firing up Media Center, it couldn't find
the tuner-settings, even after driver was reinstalled after reboot. So now i
need to set the tuner EVERY day, unless i do it the American en not so GREEN
way and leave the machine running 24/7. Hybernate doesn't work as the
screen pops up 99 error-messages from "dll-hostprocesses not working" when
waking up because the network connection takes forever to build.
I love this WOW-experience, NOT
