I have had this problem since Channels has released Commercial skip! ABC news has never worked well. The biggest problem is from about 18 minutes into the program there is a blank(dark) space from that point until the end of the program. No interment brakes where commercials occur! Just one blank space so I fast forward till I return to the programing. Not horrible but not how its supposed to work! Also For News is bad from start to finish! Commercial brakes where there are none and vice versa! Most other channels work fine! is this what most of you are experiencing?
Are you talking about the ABC News Live channel? Or ABC World News Tonight?
ABC NEWS TONIGHT with David Muir!
Hmm 
That does seem odd. Do you have your logs or anything so we can take a look? Do you have tuner sharing on? What devices are you using? What version of the apps?
My main question is whether my situation is normal for the rest of you or is my problem just on my setup? I can get the logs, Tuner sharing is off, I am using Shield TV with Homerun Quatro, and not sure what you mean about version of apps, Channels is up to date.
