Cable boxes' signals compared to cable modems' signals..

Cross-posted to 5 groups.

Hello.

I was at my parents' place again, and was noticed some of their TWC's 
digital channels (e.g., HBO) were not always clear (pixellated, 
corruptions, etc.). It didn't matter which room too, through HDTVs' 
tuners or TWC's Motorola cable boxes, etc. I looked at Motorola's 
diagnostics and confused on how to read these technical info(rmation) 
compared to cable modems. There's a lot more than cable modems'! Am I 
only looking at their download and upload streams? I don't think I saw 
any SNR values? There were a long menu list of options!

If it is a low signal issue due to very long coax cables and many 
splitters due to the size of their place, then what's the best way to 
fix it? Put a signal amplifier in where the TWC coax cable enters the 
building? I remember they had issues with their Internet and phone 
services due to signals even when TWC technician was installing a few 
years ago. I assume the switch over to all digital and losing analog 
(they still have analog and some free digital QAM channels) will not fix 
this issue?

Thank you in advance. :)
