I have comcast cable and I always see that the games will be in HD, but rarely get them. For instance tonight it says it is in HD, but it says off air when I go to FSNSU HD. I also don't think I get sun sport HD which was the channel it was supposed to be HD for the game last night. Do I need to call comcast to request the channel, and why no HD tonight on channel 401 FSNSU? Please help.
