hi,

I had/have the same problem
I found out that this feature produces the problem:
 Visualization: goom

if I turn it off I can switch to radio-channels and listen to it without any problems

Halim, the code lines you posted looks like a new a/v sync method
if "Visualization" is set to "goom"
xineliboutput or maybe xinelib adds some frames to the video stream

hth to solve the problem
