Hi Roman,
Sure I remember. Thanks for the hints. Interestingly, there's also a tv
channel associated with the same people and the url is:
http://85.92.138.40:8000/;stream.nsv
It's called Tramuntana-TV and it's streaming perfectly (both video and
sound)
Both video and sound are fine.
The other stream that I talked about in my OP is basically audio, it's a
webradio station with some accompanying eye-candy. I can't any sound. Both
use faad.
Here's the output from mplayer run in console:

Notice that the "Opening audio decoder" sections are identical; but one
works (the 2nd) and the other doesn't (the original one). There are some
differences in the first section, e.g. in the 2nd working stream:
Bitrate: 300kbit/s
Cache size set to 320 KBytes
Cache fill: 5.00% (16384 bytes)
In the original non-working stream
Bitrate: 300kbit/s
Cache size set to 320 KBytes
Cache fill: 2.50% (8192 bytes)
In both cases faad is used for the audio and it seems to work, at least in
the 2nd case.
Cheers,
Jonathan
