I find the new Local Radio Station application to be really flakey:
It stops randomly and regularly. You need to go back to the Guide to start your selected station again. This will happen several times in an hour.
You can not get out of it. When you go back to the Guide to select a different channel or service, it simply returns to your local radio station. The only way I've found to get out of it is to 1) shut Optik off, 2) restart Optik, 3) in the initial startup screen tab right to get to another suggested channel and select it, 4) once that channel starts then go to the Guide and 5) finally select what you want. Messy!
How long till we get a better version of the Local Radio Station app??
