Brooktrees would be nice - if you could find them. Given the move to DVB
is nearly over, there aren't many analog cards available - or need for them.
The new cards use incompatible chipsets (learnt the hard way), including
analog and especially DVB; you have to use the cx88 port to use them. Or
if you come across a different chipset ensure the card is USB based and
use webcamd.
Following all that, FBSD works beautifully as a HTPC.
