Just received my Chromecast with Google TV and am trying to use it with the provided Sling TV app. If I am watching an OTA channel (using an AirTV Anywhere) I get major buffering on the Sling TV app. The other streamed channels work pretty well, just that the OTA channels are bad. Anyone else with this setup and having the same problem?
I have the same issue. I never found a solution so I stopped using it and went back to my Roku where I don't have that problem.
... I also tried it on my old Mi Box 3 and it doesn't have that issue either.
