The way it worked with ATI All in Wonder PCI, is you could possibly use it with a secondary display but the TV Tuner had to be on the primary dispaly for it to work (If you set ATI as secondary the TV tuner would not show up on any monitor). So, with the card here I assume it's also the same situation... If it even works with multi-display in w9x.
Not bad for an old system that isn't going to be used for games.
