have just received and installed my all-in-wonder 8500 dv graphics card. i still can't get DScaler to work with it. do i have to have a tv signal going through my card or some kind of picture signal? also, just checked the help files with dscaler and found that the card is not supported, or has the list not been updated to include the radeon chipsets? please help as this will have been a very expensive mistake!!!
