I attempted to watch a new channel that just officially started yesterday. I have watched several programs on the beta version of this channel including a streaming program and it was great. Yesterday when I attempted to watch something whether it was live stream or or not the screen would flick like it was going to play then jump back to the screen where you selected to watch it. All other channels work fine. I tried reloading the channel, no luck.
Why didn't you name the channel?
Assuming it's GBTV, it's probably suffering under the load of higher viewership. This is very common with new channels, because the content providers don't always allow for such high volume. It's probably up to them to fix on their side - there are only so eels you can fit through the pipe at once.
