A person in another forum indicated that he was having problems with HBOGO after upgrading to 8.1. I went to the HBOGO site and I can hear the video but no picture. The site does not give an error message to indicate the problem. If I go to my xfinity account I can view HBO content. It seems that HBOGO is more geared towards apple and android devices. Anyone else experience this? My tablet is the surface pro 2 128gb version. I don't know what the other person was using, but I'm assuming that it was a surface as well, since he posted on a surface site. Never mind, must use software rendering in the internet explorer internet options instead of gpu.
