Thanks so much! It worked for me!
I unplugged the Roku overnight and tried again this morning....loaded the youtubetv application and it worked.
Apparently just powering off and on alone did not clear the problem.....but leaving the roku completely unplugged was the solution. Something for the developers to look at....
