AFAIK there has been no indication yet by ATI that they intend to provide a
software encoder package that will permit the tuner on AIW cards such as the
ATI X1900 to be used with Media Center on Vista.
I could installed Vista b5384 with minor difficulty, i.e. need to press F8 &
safe mode even during installation. After installation, I still need to use
safe mode to go into Vista. Otherwise, going to normal mode, the PC hung.
Any idea?
I suggest that you boot into safe mode and from there disable/uninstall the
TV tuner componend of your AIW card using device manager. Then reboot and
see if you can run Vista without the tuner component.
In fact I could not use the coming-with AIWx1900 CD driver for installation
so the tv tuner driver & software were not loaded. I tried to manually
'update' the driver (display driver only, not tv) by going to the driver
folder of the CD, but the result was same. I even tried to use Radeon x1900
driver, and the result was same - i.e. PC hung after the startup logo.
I know there is no VISTA driver for the AIW card what you do need is the ATI
driver for the X1900 graphics card so that you can use the graphics 1/2 of
the card without using the Tuner 1/2 of the card. Each part of the card has
its own driver.
