I upgraded to the new version of Beyond TV because it supports HD. I got an over-the-air tuner too, the point being that I can at least record more than one thing at once (since the networks schedule like the two shows I want to watch at the same time).
Of course, I don't actually have an HD monitor, so I'm not really watching in HD unless I transfer the files to my desktop. I was disappointed that my NBC affiliate's signal is too weak to get with the little indoor antenna. I looked them up and they're only transmitting at 7kw, which is weak. I had a hard time at first getting good signal strength because I couldn't find a good piece of RG-6 with good connectors.
It's kind of neat to see that TV is finally starting to transition to HD in a more sincere fashion. There still isn't a ton of HD content, but the networks are at least doing their prime time stuff.
