I purchased a new Samsung UN46D6500 T.V. on the weekend. The HD quality is MUCH better now than with my old 42" Toshiba plasma. The quality I see now, is much better than satellite every was.
As for channel changing, the RT-N56U runs circles around any other digital service out there. It's almost as fast as analog cable channel changing. The RT-N56U brings back true channel surfing again.
But, Bell TV (satellite) PVR is still miles ahead of our PVR. Not complaining, just stating my opinion.
