The problem started for me when iview forced me to sign about two weeks ago. I set up an account, linked to the tv, selected a show and the video wouldn't play. The wheel just kept spinning . It worked fine the day before when I didn't have to log in. I tried relinking the user, reinstalling iview, rebooted modem, checked tv updates but nothing worked.
Finally I got sick of not being able to watch anything so I reset the tv to factory default and reinstalled iview, which fixed the problem. Now I just have to hide all the of the shopping channels and install the other apps.
