TV-out on Win2k and Margel G-200

[blackjack]

Does anyone have the TV-out working with the Marvel g-200 and Windows 2000? I *swear* I had it working before, but then I started tweaking stuff to try to get the other Video Tools working and I can't seem to get it back. Right now I'm running the 5.00.07 beta Poweredesk drivers with no video tools installed, and tho the "TV Output" tab is there under advanced properties, if I check the "Output to TV" box, it just unchecks itself and nothing happens if I hit Apply or OK. The "Information" tab shows that the tv-out (and the rest of the Marvel hardware) are present. Hrmph...
