History Channel programs don't play & ABC loses audio (Roku 3, but not Roku Ultra)
Relatively recently the audio in the ABC "app" has started cutting out (as mentioned in another problem posted) and it is almost always triggered by specific commercials. Those commercials are for Rosanne and American Idol. There is almost certainly something different in the encoding of those particular commercials that triggers the problem.
The problem exists on Roku 3 (with latest firmware - checked and nothing new arrives, 8.1.0) but does not exist on the Roku Ultra (also with 8.1.0). There is almost certainly something that the newer Roku can process that the older Roku cannot.
Also, using the DirecTV service login/activation a LOT of the cable type channels do not work right anymore on the Roku 3. When an episode is selected in the History Channel the channel/app closes and the Roku goes back to the Home view. Same thing with A&E. They have the same type of channel style, so are probably made the same and have the same problems. They work OK on the Roku Ultra though.
