this has been bugging me for a while, but since it happens on channels I
don't usually watch, I didn't ask before.
There are some channels that are completely unwatchable: even with a
perfect signal (at least according to femon) I can only see blocking
artefacts and chirping sound.
I tried vdr-xine, the dxr3 or vlc/mplayer through streamdev, the result
is always the same.
Here are some of the channels where this is happening right now:
(in fact all polish channels on this transponder do the same)
and many more.
