Digital TV signal

[Nutritious]

Hey guys,

We just bought a new TV in preparation for the digital TV cutover coming in Feb. Because of it, we're getting quite a few new "digital" channels that we hadn't before via our antenna (no cable at home). Thing is, frequently the picture and/or sound is freezing up or sometimes pixellating while viewing digital channels. Old analog channels work fine, as well as the DVD player - it's just the digital ones.

I'm assuming it's a problem with the signal or something, but I'd really like to get it fixed before the cutover occurs. Is it because of our somewhat-old antenna can't handle the signal efficiently enough? Is there something else I need to be concerned about?

I've had a similar issue, but the problem was probably external, as it went away when we switched provider.
