MTV2 compression levels

[brewtownska]

I'm a TWC customer, and EVERY time I've gone to watch anything on MTV2, the picture is very blocky because of the compression.  I'm curious if anyone has any experience with this channel on other cable systems or satellite, whether this is how MTV2 sends the signal, or if it's TWC doing added compression to it after the signal is received.  The past few days there have been some live bands on at 8pm, and I'm really getting annoyed with how horrible the picture looks.  Anyone else with any input?

Has to be a TWC problem...picture looks fine on Directv.
