RokuJohnB Yes, I did all those things, and eventually it began working ok again. However, there are still glitches like this happening, from time to time, including tonight. The channel guide said "No Information" on every channel, and wouldn't go higher than just the OTA stations. So I did a system restart, and it once again was working OK, although it took a few minutes to get the correct time...
The glitches that are constant, are mainly when I'm streaming on my computer. The picture is too dark, even when I turn the computer's brightness up. Also, the captioning is on, even when it's not selected. When I change it to setting it on, then off, it will turn off, but than a few minutes later, the captioning comes on again, really weird.
On my Roku TV, my main complaint is that movies on demand, that say in the Guide, "click * to start from the beginning", will start from the beginning anyway, even though I don't click the asterisk! When that happens, it also cancels out the back feature, so I can't go right back to the channel I was watching, as I may have just wanted to see what else is on, during a commercial. Why do they go back to the beginning, even though I didn't click the asterisk key? Why can't this just work right?
Oh, and it seems every few days, when I am on the Roku channel, if I click on one of the movies' trailers, I'll just get the spinning circles, and it'll say either 0%, 69%, or 99%, and then nothing else. If I try to play any of the movies, same thing happens! And sometimes if I go to Netflix, the same thing will happen, usually when I've had this issue with the Roku streams. The only way to fix it, is to do a system restart... It seems like it could be a matter of a build-up of cache, is there some way we can just clear the cache, instead of having to restart my Roku TV?
