brought home a 42 Panasonic Plasma G25 series in December. Hooked up to my new QIP 6200 STB from Verizon FIOS. All is great EXCEPT distortion across the very low band. Difficult to describe, maybe an echo or like the sound you here talking through a moving fan, but only in the low band. Voices are OK, but with the background audio it is a constant double talk on the low end. Panasonic suggest a compatibility issue between the QIP 6200 and the TV. Something about PCM? STB has no settings to modify audio format. I use HDMI cable between STB and my Panasonic plasma.
