If your Premiere is brand new, then you would think that the power supply would be OK, but who knows. This person had pixelazation and fixed it by replacing the capacitors.
"I can't believe this worked but it did!
Have a philips dsr708, pixilation to the point of second tuner being near useless most days, driving me bat chit crazy and getting worse over the last few months, incidentally it was always worse the higher the channel #was. Put a 470uf 35v on the chip (I may go back and move\mount it elsewhere) pins just as instructed here and poof problem appears to be gone, only been a few hours but hopefully it last till Dtv get's their act together with offering another tivo unit.
It maybe a tedius PITA to get accomplished, but it works.
THANK YOU EVERYONE "
