Has anyone else had the problem I am having with the DD 5.1 audio on ABC's network shows via KOVCO HD on Cox? There is a +4 dB boost on the center channel and slight buzz in the overall audio. The result is that I have to keep the gain of my receiver, a Yamaha RX-V3900, at a low level, compared to its setting on other channels, to keep the dialog at a comfortable listening level. Even then, the overall quality of the 5.1 audio isn't very good.
By contrast to ABC's shows on KOCO, DD 5.1 audio from Fox, NBC, and CBS, via their local affiliates on Cox, have center channel settings, which are never greater that 0 dB and, often, -2 dB. Also, the 5.1 audio from Fox, NBC, and CBS always sounds great. This makes me strongly suspect that the problem I am experiencing with ABC shows lies with either ABC or KOCO HD.
