These Smart TVs have very limited browsers and if the web site wants Smart TV viewers via the browser they need to test the content. Remember the Smart TV limited browser discussion is rather well done so let's not repeat this again. Here's a link from a prior discussion on that.
I was watching college basketball over the weekend with a Samsung Smart TV via the web browser on ESPN3.com. Watching the game was great but when commercials came on, that is when everything became a disaster. The commercials would hesitate and when they were over, the screen went blank and the game did not come back on. So I to refresh the browser and reselect the game to keep on watching. I tried both wireless and wired to get on my home network.
Any suggestions for me to try on my end?
