When I tuned to HDNet this morning (the Detroit parade), the FIRST thing I noticed was degraded PQ. It wasn't until much later that I looked over and saw the 5.1 indicator on my receiver. I have monitored throughout the day and have seen much more "graininess" in everything and not the "WOW" type of PQ I am used to.
Has anybody else noticed this, or do I need my eyes examined? If there is, indeed, degraded PQ and the cause is the 5.1, then I'd take 2.0 anyday.
