Please put my mind at ease - pixelation normal on my setup?

Here's what I've got setup:
- 52" Sony xbr9 lcd hdtv (about a month old)
- TiVo HD dvr (about 3 weeks old)
- verizon fios HD service
- all connected via hdmi from monoprice

so I can't help but notice pixelation when there's a fast moving scene like a quick panning of the camera. I especially notice it when there's quick contrast in light like in an explosion. Slower moving movies look gorgeous - sweeny Todd for example looked awesome. I tried watching speed racer the other night. With all the quick movement it looked terrible. I've read that it could be more a product of the signal from verizon. The compression causes it? I just want to be sure that that's the reason and not anything else. Thanks in advance for any replies.
 
p.s. could it be the attenuator that was installed?

Time Warner and Viacom deliver their premium movie channels (HBO, Cinemax, Showtime, etc) with relatively high levels of compression, so you will see compression artifacts on those channels during scenes with lots of movement.  When recording from premium channels, you may want to use the main east and west feeds when possible, as those tend to offer better picture quality.

 

Channels like ESPN, TNT, and Hdnet use less compression on their channels, hence they exhibit fewer compression artifacts.

 

On the TiVo, there's a relatively simple way to confirm whether the pixelization is part of the original picture signal.  While tuned to the channel, open the Messages & Settings -> System Information -> DVR Diagnostics screen.  If you see millions or billions of RS Uncorrected errors, then the source of the problem is signal related.  If you don't see RS Uncorrected errors incrementing by the millions, then you are seeing the picture as it is sent.

 

Note some TVs and certain settings on some TVs can make compression artifacts more obvious.  If you have not done so already, you might try these settings for the 52XBR9 used by Cnet in their evaluation.  You might also bookmark the AVS XBR9 thread.

If you are the original poster (OP) and your issue is solved, please remember to click the "Solution?" button so that others can more easily find it.
