I recently began experiencing issues with my NBC affiliate channel (KCRA in Sacramento) on both of my Directivo's. I own a HDVR2 (with an upgraded 120 gb hd) and a Samsung SIR-S4040R (with an upgraded 160 gb hd). Drives were self installed and purchased from Weaknees. The audio is very low and I have to turn the volume up on my surround sound 8-10 levels higher on that channel only. I have listened to the sound of that channel on other TV's, non-Directivo systems, and the audio seems fine. Has anyone experienced a similar issue? Particularly those from the Sacramento area.
