Roku no longer streaming all channels

As of yesterday morning, my Roku is no longer streaming all of the channels.  It appears only weather and some other channels I've never watched. It was strange that it was working in the morning then, after turning the tv off and turning it back on, it stopped working.  It seems as soon as it switched from Beta to production Stream, things started going wrong.  I still can't get my video and audio to match up after much troubleshooting on these forums.  Any help would be greatly appreciated.  Thanks
