The ABC 11 engineer told me that it has to do with the (software) code sent to them by Dish. It cleared up on ABC when they sent a new version. Apparently, the version sent to Fox 50 is funky. One of the many reasons that I'm dumping Dish this month when my contract runs out. Time Warner is way behind with the number of HD channels-- but the ones they don't have (except for NFL Network and one or 2 others) that Dish does-- are mostly stretch vision. TWC has some that Dish doesn't as well-- like MLB Network HD, Speed HD and ESPNU HD. But, the most important thing is that at least they (TWC) tries to communicate. They post their channel additions weeks before they launch. Unlike Dish-- which just leads you on and then never delivers.
Also, I'm getting sick of the signal going out every time it sprinkles. And, I'll save about $60/month for 6 months (by bundling phone/Internet/cable), and then $40/month after that.
