Hi all I'm having problems with my TBS 5980 USB DVB S2 tuner, with it freezing when changing channels in WMC (w7 64 bit). All the drivers are up to date, and this is the second one I've had after sending the first one back. Either I'm very unlucky and have received a second faulty one, or my system is causing the problem, or the product is flawed! I'm running a new Acer revo 3700 (win 7 64 bit, 3gb ram). On the first tuner I had, it would always freeze after around 30s of constantly changing channels. It did it in WMC and another DVB viewer software (can't recall which). The new one does it less frequently, but is still averaging a daily freeze, which is very annoying So, given that I'd hope TBS would not just sell flawed products, does anyone have any suggestions for things I could try? I'm about to give mediaportal a try, but I'm not holding out much hope... Any help greatful received!
