I have the Tivo running to a 47 inch HD LCD that goes up to 1080p. I set the Tivo to 1080i fixed. (changing this does nothing). Ive tried Component and HDMI. Anyways for a couple of the HD channels I have either a bright yellow line running down the very left side of the screen or some strange oscillating bars at the very top. All of the SD channels on fill have some black lines on the left and right side. Also channel 30 (on cable) comes in but the audio isnt there just some light scratchy sound. Is this normal? I dont really mind the lines on the SD signals as they are black and I dont really notice them. But the HD channel problems are quite annoying. Some HD signals are GREAT, but there are others that come in with those problems over cable AND OTA (same channels). Is this a problem with the tuners? There is another cable box in the house that tunes those HD signals just fine. Is there a way to fix this or should I just take this one (the second) back? I took the first one back because it kept crashing and pixelating some HD channels but did not pixelate on playback. It also kept rebooting. Not using any cablecards either. Thanks in advance for any help.
