I set my Comcast DVR to record the Today Show on 2/1. I wanted to catch Sheryl Crow. When I replayed it I saw that it was in SD. Scanning through it I noticed it went into HD for a second or two then reverted back to SD. This happened for the first 2 hours plus. We had bad weather in the Phila. area so the local station ran a banner across the bottom of the screen with school closings. After coming back from commercial breaks the show would be in HD for a moment just before that banner appeared. This was knocking it out of HD. Banner was on constantly until about 9:30 ruining the show. After that it was dropped and HD picture returned for rest of show. As a result I only got 1 of Sheryl's 3 songs in HD. Has anyone else run across this type of thing. Can't the engineer get around this problem? I sent an e-mail to the station. No reply.
