Note the for last few days channel 3 (tuning ch0001 or 0306) are HD and not displayed on our 720 TV sets. Display is normal on 1080 TV. Anyone else have such issues? Not sure if because of the channel 3 issues with payment of fees or something else as just started about 3 days ago.

Have found GMMZ channel 43 broadcasting what must be Ch03 non HD programming. At a loss to explain why no video or audio on channel 1/306 using older TCL 32" LED but working fine (with same sat box) using a Samsung full HD TV.

OK appears the new OTA update removes access to Channel 3 on both Ch01 and Ch306 for GMMZ box. (although they are still listed as tuned in). My 1080 TV had not been updated as never turn box off; but after doing so no longer have a picture at Ch01/306.
