Thought I'd create a list of HD channels that do *something* to reduce the quality of their broadcast over what it should be.

CBS/WIVB & CW/WNLO - Recently started upconverting SD programming's stereo soundtrack to 5.1, and in doing so the center dialogue channel is now duplicated to every other channel on all programming, including native 5.1 shows, resulting in an effect where voices come from everywhere. Due to this the audio track now sounds compressed and jumbled.

Global/CIII - Noticably softer image than originating networks. Several audio issues on all programming: too much bass, giving it a boomy/muffled quality. Rear channels appear to be delayed over front channels, resulting in strong echo effects when the original program is trying to itself create an echo (such as in Bones - their lab sounds like a stadium instead of... a lab).

City TV - Several audio issues on all programming: somewhat too much bass; center channel dialogue is soft; rear channels are both too loud and delayed from the front channels.

ABC/WKBW - Audio issues only on 2.0 material upconverted to 5.1: the center dialogue channel is duplicated to all 3 front channels (sort of like Pro-Logic II Music mode). Original 5.1 programming, however, is fine. Also does not yet show syndicated shows (such as WOF/Jeopardy) in HD.

NBC/WGRZ - Still broadcasting in 2.0 stereo! Besides for this omission, their audio and video quality is absolutely fine.
