As both analogue tuners have hardware encoding, these should be supported due to the design og TVServer.
Furthermore, TVServer supports any DVB and ATSC cards w/BDA drivers, so these should work as well.
So my guess is that it is already supported
(Sometimes hybridcards can be a bit PITA, though, and this has 2 tuners + 2 receivers, so ...)
TVServer supports more cards.
