Is anyone in Boston market having transmission problem with channel 630 NBC Sports Boston? I have one TV connected to an HR22 where the video and audio is cutting in and out. I have not found another channel with the HR22 that is having this issue. To make it more weird I have another TV connected to an HR44 that has no problem on the channel. Any ideas why one specific channel on one specific TV would have this happening? I have already rebooted and refreshed receiver and changed HDMI cable just to rule things out.
