Several web references suggest the card may use a Brooktree BT878 chipset (and one ref found a Philips logo on a Tiny TV card, though no name - see Tiny drivers - this was a 1999 UK Tiny PC).

If that is the chipset, you might look at this at Sourceforge, which (at a quick read) may provide a driver that will handle a card with that chipset BTWincap.
