Sorry to jump in on your thread. What is the model of the usb tuner you are using. And would you say that the quality is good from it. I'm looking for one for my system, but not sure which one to go for.
100% agree with that the bundled WinTV is garbage, I bought the Diversity USB Nova TD so I can use it with my Vista MCE but also so I can use it with a standard XPPro Laptop when on the move.
Just set it up with Vista MCE and it works a dream, had a go with the bundled WinTV on my laptop and I was horrified how bad it is. I was about to have a play with the free Mediaportal when I remembered I bought a copy of Showshifter back in the day before they went bump. I've now loaded that onto my laptop and that is working well again. Although as I can see the Winter Hill transmitter from my house the picture is superb, will have to see how it behaves when I'm on the road.
