I've had my 64h14 for almost 2.5 weeks now. Everything works fine except for when it gets too busy. Like the other day I was watching INHD and they were doing a program on fireworks. When it starts to get busy like alot of fireworks going off the picture seems to breakdown. Like those digital squares that you would usually get with digital cable every now and then when switching channels. Is this normal? Other than that the PQ is awesome on HD and DVDs.
This is normal. See the FAQ on "Acronyms" for the definition on "macroblocking".
Macroblocking is caused by the limitations of MPEG compression. You can also see this when viewing an SD channel with too much compression.
Nothing wrong with your TV, although a proper setup will minimize macroblocking - see the FAQ "What you need to do to your new HDTV".

I already used the DVE disk to set up my TV. I did the black, white, blue, and sharpness. I think that's all there was to do on that disk besides the audio.

What is your source for programming?

Component cable off the Comcast Motorola box.

Call Comcast andcomplain about the signal strength..
If he's got low signal strenth, he'd have pixellation on "borderline" signal strength stations. What he described sounded like macroblocking, which is not affected by signal strength whatsoever.

I don't think it's signal strength because like I said I only does that when it gets really busy on the screen. Like when 50 firecrackers explode at once on the screen.
You'll notice the same sort of thing with scenes with a lot of action, or movies with lots of "cuts" or nature shows with flocks of birds.
MPEG does a pretty good job of compression under normal circumstances, taking a signal of over 1 Gb/sec and compressing it to 19 Mb/sec (a compression factor of over 50), but when there's too much change on the screen, it just can't keep up.
