I'm having the same problem and had it last year too. The picture looks better to me, though.
It's not because of your wifi, Mikedub, because I have a dsl modem (am getting a modem with wifi installed soon, whenever I get off my butt).
Last season I wrote to LP and they game me a ticket # and then within a day came back with a 'solution', which helped to cut down the number of freezes, but I still had them.
I'm getting ready to write them today and tell them of my problem. If everyone does that, maybe they will work harder on the glitches.
