Advertisements I am a long time user of the S2 which has and still runs nearly flawless. I now have a S3 which has been trouble since the beginning. I have very frequent pixilation/tiling which make it difficult to watch most shows. It occurs nearly every show I watch, and can be on any channel including HD and high number digital channels, but does seem to be more common on standard lower channel numbers. It will occur on both tuners. My pixilation will last anywhere from a few seconds to several continuous minutes and is associated with audio dropouts. Now Ive seen brief 2-3 second tiling with digital cable boxes and with S2, but they have been very infrequent and never long lasting. As reported elsewhere, with removal of my cable cards, this issue resolves with the analog input. I have switched out the cable cards, tried switching component to RCA (red/white/yellow) cables, and used 2 different TVs with continued tiling. After much discussion with TiVo customer support, I had a second S3 unit sent out .which resulted in the same issue. I began to suspect signal issues as nearly every cable tech (including internet cable guy) has commented how strong my signal is. Nobody admitting it is too high, but at upper limits. I thought maybe running the cable through a power surge protector would alter the signal strength (I thought decrease, but Ive had someone tell me it bumps it up since). Well, this change resulted in constant tiling also worse in degree of tiling. Of course the new software upgrade made no change Well I had another cable visit yesterday and had a sympathetic tech who stayed for a long time trying to sort things out and was on the phone calling others as well. He climbed the street pole to check incoming signal, checked the box just outside my house, checked the signal inside, and even ran a brand new line from the street to my house. Nothing changed as together we watched the tiling continue to occur. Of course all the while I have no problem with S2 in another room. He felt the signal at the street was too hot and called in a maintenance order which miraculously occurred later that same day. I watched from my window as this maintenance dude climbed poles on the street checking signals. He was cool and actually came up to my door and told me the signal outside was too hot for specs and he decreased the signal (I think he said by 4-5dbs). He thought maybe it could drop it another 1 or 2, but he was worried it would affect other neighbors. Well, it seems to decrease the frequency of the tiling but it still occurs and interrupts most shows. Ive noticed that if I run the TiVo diagnostics during the tiling, the signal strength fluctuates tremendously (maybe 60-80s) and the signal lock flips on/off. Typically all my channels are 94+, but occasional 89-93 without tiling. I am running out of ideas. I remember seeing someone mention a terminator resistor on the antenna input which I guess I could try. Of course TiVo tells me to keep trying new cable cards, with a rep on the phone yesterday telling me his tech supervisor has a S3 and had to go through SEVEN sets of cards. Anybody have any suggestions? btw I use Cox cable in Hampton Roads (Norfolk to be specific) with Motorola cards anybody from the area with similar issues or with success?
