I am also having this same issue, if you select a USTV Now channel, it just stays on the channel it was before. I am using the 'USTV Now' addon in this forum at the beginning.

Are you able to watch streams in the actual USTVNow plugin? If not, that may be the issue.

So I tried opening the USTV Now app directly and it worked. I went back to PTVL and tried it again and my channels work now! Not sure if I needed to run the app separate for the first time or if just sitting overnight fixed it in some weird way.
However, now I'm noticing that the PTVL guide for those channels are incorrect. The guide says "The Young and the Restless" but playing is the Ellen Show. If I go back to the app, their guide is correct, stating Ellen is on. Is that something that will self correct?

are you using development or stable PTVL? If stable, try development and force channel reset. let me know if it's in sync... if not let me know your timezone and how off the epg sync is...
