Unique On Demand Signal Problem
A couple of days ago a unique (I think) OnDemand problem began. This issue pertains only to the OnDemand via internet and using my main laptop. OnDemand via cable box using TV is fine. The OnDemand signal is breaking up, pixilating, etc. Basically unwatchable. Audio is fine. Changed ethernet cord and also tried wireless--same problem. But signal is fine using secondary laptop and smart phone. So you would assume problem is with laptop? But signal is otherwise fine at all other web sites viewing videos. Also fine viewing Amazon Prime movies, etc. So appears isolated to Comcast OnDemand and on this particular laptop. One would assume that if I could watch other videos and also Amazon Prime streaming video, I could also get a good signal from Comcast OnDemand. Any thoughts on this problem?
PS-Watching live TV on Comcast via internet on same laptop is fine. So problem is with OnDemand only!
