I know the ultimate response is to contact Tivo directly, and I'm sure I will. But I wanted some consensus of some things to try or do first. My new Premier XL records shows and when I play them back, sections are so pixelated, frames freeze, slow jerky playback making viewing the show not possible. Usially happens for several minutes of show then plays normal. I want to know when I should be concerned about a warranty replacement. I know digital signals produce pixelation, but I have not seem this type of display while watching live tv (which I rarely do anyway so I dont really know). Is there a way to test hard drive to see if it is a bad drive, has bad spots. I know Tivo will have to handle this, but just wanted heads up. Thanks.
