Recently, bought the Visio 50 inch plasma display. Hooked up the comcast dvr/hd box to the display using a dvi to hdmi cable. Receives an excellent picture on the premium channels (HBO, Showtime, etc), a decent single on the cable channels (espn, cable news, etc) and a poor single on standard local channels (ABC,NBC, etc.). Is this normal for the signal coming from Comcast? Any other comcast users have the same experience? I don't believe it's the display since the premium ch. and dvd's are detailed and sharp. This would be a big disappointment if the cause is Comcast and I have to live with it or switch to Sat. !!!
Any thoughts or experiences would be appreciated,
note: during the initial power on of the display the local channels were awful, but after about an hour or two the signal significantly improved. But, not enough to be happy about.
