1. Very well in my area, YMMV.
2. Signal Strength varies between the channels. I get good signals on all the broacast channels. Good signals are not always broadcast however.
3. Its basically the same quality as long as you have a clean interupted signal..its digital.
4. I've not had a chance to try any encoding of the files, nor do I use xvid. I'll try some encodings when I get a chance soon.
5. No subscription, its a free broadcast. Check TitanTV for the broadcasts in your area.
6. ATI sent me one to test, no cost to me. It was extremely late in the beta process, so with my vacations and such, I've had little time to check it out. I was watching the Olympics this last couple of weeks when I did have time, so I didn't play around much, just watched.
