I just had to put this out there. Being many have taken the time to post for the first time. It could be dissatisfaction or something else.
I know many may be FiOS customers and just simply do not like the changes in 1.9. I think some saying they are going to go to Comcast, may just be Comcast customers anyway.
I love the new guide, and yes it was tested extensively!
There may be some issues depending on the model of STB hardware you have, or the settings on the box or your TV. But I believe it is far better than what we had.
