Has anyone used a Compro S900 DVB-S/S2 USB tuner? I'm putting a graphics card in my one PCI slot, so I can't use my PCI tuner (Compro VideoMate S300) any more, I have to go USB. The Compro PCI card has server me quite well, but the Compro drivers have been a bit flaky at times, and there don't seem to be many reviews of the S900. I'd appreciate any opinions on this tuner, or suggestions for a similarly priced alternative.
