Does anyone know if Tivo corrected their pixelization problem with their HD dual turner Tivo unit. Last summer I bought this unit, but after 20 minutes every channel looked like a jig saw puzzle. It was not watchable. I called Tivo and they said they are aware of the problem and are trying to update their software to correct the pixelization. I waited for about a month, but it was not corrected so I returned the unit. Enough time has gone by now, I wonder if it got corrected. I would like to get another HD Tivo unit. Can anyone update me on that issue? Thanks
