Greyed out Catalyst Options

System specs:

New build PC, AMD 64 bit chip, ASUS A8N-SLI Mobo, ATI X800 PCI Express video card, Winfast TV 2000, Dual CRT 19" monitors, primary Viewsonic, secondary Sony.

Catalyst 5.5 installed, Hydravision installed, latest leadtek/winfast TV card drivers and apps installed.

I'd like to be able to put the TV screen on the secondary monitor...and am unable to do so. On a previous machine, that was no problem. Leadtek has no information on dual monitors [except for the 2000 XP card]...Same thing happens when I try to move a DVD player window to the secondary...

If I take the TV/DVD picture on the first monitor, and attempt to slide it over to the second, the display is black...if it gets moved all the way to the second monitor, the app freezes.

In searching ATI's site, it seems to be a "video overlay" adjustment issue, but when I get to that portion of the catalyst software, all the options are greyed out.

On my other machine, a 64 bit, same TV card, but with the Radeon 9800, this has never been an issue.

Is there a solution for this? Or did "upgrading" to this version of graphics card mess up the ability to move the TV/DVD movie display from one monitor to the other?

Thanks in advance for any help.
