According to Technotrend's web site the BDA driver for the TT-3200 is compatible with 64-bit Vista. I'm using mine on XP though, so I don't have any personal experience.
Skywalker-1 works under VISTA ultimate, with Tsreader and DVBdream. However, I went back to XP, just to avoid all the Vista native issues. I don't like that OS very much at all.
ProgDVB 5.14.08 works with windows vista 64 and has old WDM driver for 102G. I use the BDA 878 driver with my Twinhan 1025 pci card. It's freeware but to run DVB-S2 you have to buy the pro version. I get stable HDTV on his software.
