Steps to reproduce:
1. Start mediaportal in full screen
2. Select My Radio
3. I then select a channel and after about 7-10 seconds the UI freezes

I have to exit mediaportal to gain control again.

There was another thread sometime ago that mentioned a very similiar problem. It maybe back again... https://forum.team-mediaportal.com/pre-1-0-rc1-273/playing-dvb-radio-channel-gui-freezes-28232/
