It always is a challenge when upgrading the PC to get the HTPC setup the way I want. I recently built a new computer and needed to change the DVBS2 tuner from a PCI to USB or PCIe since the new motherboard doesn't do PCI. I have been using a TeVii S464 PCI tuner. I was ok with it's performance and it functioned the way it should. New computer, so I thought I would try the TeVii USB S662. Whoa! that was a poor choice. The tuner in that one is a joke. Other than that it was just like the PCI tuner. Well it wouldn't be easy but I can stick a PCIe unit in there. They all use the same driver and should be a snap software wise. Well I get a S471 PCIe. HMMM, TeVii doesn't list a S471, just an S472. Well stick it in there and fire it up. Looks good. good performance, and then I see the bug. It doesn't power down the LNB when you stop using it. In fact it's hot anytime the PC is on. That messes up my dish sharing setup among three receivers. Always something in this hobby. And quite often a "Domino Effect". You can't just change one thing, you end up going thru the whole setup.
