My receiver in the single mode has a blury picture. The guide is not sharp like it used to be the hd channels are not what they used to be. To verify this I played back some hd stuff from the hard drive that I recorded before yesterday and it is very sharp and now channels like HDNet look good to be optimistic. Only our channel 11 NBC from minneapolis has good hd right now 5:03 PM with live news the rest is just plain shity. Boo
Have you tried something from another source, like a DVD. Maybe your TV is going south.
