ESPN-HD Horizontal break in picture

[configsys]

I have 2 VIP 211 on both a Mits RPTV and Panasonic AE900U and I've been noticing a horizonal break in the center of the picture while watching ESPN-HD. It's not there during studio shots but usually there during the field shots. Is anyone else experiencing this and know the cause? I'd appreciate any insight. Thanks!
