I do not receive any DVB radio here so I am no familiar with it.

I tried your sample, on a raspberry pi 3 and i can hear the audio. I 
played it via "videos" by putting it in the videos directory, which 
should work the same. I press "I" and i get the info screen which shows 
the number of minutes playing.  In the playback menu I can select 
"M,playback, playback data" and see the statistics. There does seem to 
be a high CPU utilization. Is that the issue?. It shows video as 
0x0 at 29.97fps, which is a bit strange. I can jump forward and back in the 
program without a problem. Skipping to the start of the program - I just 
type 6 and press left arrow (i.e. go back 6 minutes). That works 
instantly. How do you do it?

I am not sure what else to expect. Do I have to enable interactive TV or 
something to see more? What OSD is slow? I do not see any OSD unless I 
request one from the menu, and it is not slow.

Please explain what the actual issue is.
