I just swapped out receivers and now am using a Yamaha Rx-v665. When watching tv through comcasts, scientific atlantic 8300 box, the picture will not fill the screen. When trying to change the aspect using the key, it does nothing. I've tried changing the settings through the receiver, but to no avail...any ideas??? P.S. the tv is a hdtv, 1080p.How can I fix the resolution on my TV?
Use the aspect key on your TV's remote.
