Does anyone else have the issue with ch408 on Comcast not showing what the guide says? Last night I wanted to watch the Grizzlies and it was supposed to be on 408. The game was also on the NBA network 478. NBA network blacks out the game and of course ch408 shows the Atlanta Hawks game. This happens to me every time the Grizzlies or Hawks play. It's been this way for many years now. How can Comcast not have this issue solved yet? I never know what games will be shown.
