Are we really sure that its the Tivo HD thats the problem? As I looked at those pictures that MOYEKJ provided. I became more curious. I have TWC and I have both an S3, a Tivo HD, and 2 Motorolla boxes from TWC.
For the most part I have never had any issues with "Pixelization" on any box. EXCEPT when it has rained really bad.
THEN I have that issue on EVERY box... Including TWC's DCT6412 boxes as well.
One night during a bad rain storm (From the huricane that was coming to hit Houston) I was getting "issues" but then when I looked at the picture on all my DVR's it was doing that not just on the TIVO box's but on the TWC's Moto 6412 boxes as well.
So it seems to me that it is a CABLE issue (That won't ever be resolved). You will always get some "Data" loss on occasion no matter what "Carrier" you use. (Cable, Copper, Fiber, Wireless).
So I am honestly wondering, all these complaints that I see about the S3 and TIVO HD if it isn't really just a Signal issue and not with the hardware or software.
Like I said, the only time I have seen this issue on my DVR's is during bad weather, & then I see it on ALL DVR's Tivo & the TWC Moto's
