I have a Philips HDTV that I have used with the Comcast DVR for the past year. I have received HDTV and regular cable channels through the DVR with no problem UNITL I moved last week. AFter having my cable installed at my new residence (still Comcast), I get the HD channels great...problem is that the regular cable channels are screwed up. The audio is fine but the picture has gone horizontal with a lot of lines. Can't make anything out. To make things even wierder, when I change the component in to where I normally have my DVD player (CVI) I get the normal cable channels fine but no HD!!! I had Comcast out to look at it but guy says he has no idea what the problem is. Any thoughts??? Thanks!!!
