DIGITAL RADIO BREAKS DOWN AFTER A WHILE (1 Viewer)

[pfielder]

I've set up Media Portal mostly to listen to digital radio broadcasts on freeview TV channels in New Zealand. It works fine for several hours, and then the signal starts to break up; closing down the program and re-starting puts everything right again but this is frustrating, especially if I was recording something. Any suggestions ? Also, on the radio home page there is box displaying "Now Playing" and the name of the radio station, followed by two increasing time readings with a second or two difference. What do they mean ?
