[MPlayer-users] Problem with audio

[Fabio S.]

Hi all.
I have a strange problem: if I use mplayer to watch the tv then I can't 
get the audio.

Please let me be more precise in describing the problem.
First of all, the tv works fine: I can see and ear it with xawtv.

Now to mplayer.
When I try the command

 	mplayer -tv driver=v4l2:input=0  tv://

I can see the tv but without audio. On the other hand, if I try

 	mplayer -tv driver=v4l:input=0  tv://

then I can ear the audio but I can't see the video!!!!

So, what is going on?!?

I must also say that I have a dual boot: mandriva LE 2005 / ubuntu 6.06. 
Well, the command

 	mplayer -tv driver=v4l2:input=0  tv://

works fine for mandriva: I have the problem only under ubuntu.
I installed mplayer via apt-get, using multiverse.
mplayer, on the other hand, works correctly on all avi files I have.

Any idea?

Thank you for any help

Fabio

PS: to help you, I inlude the output of the two commands (under ubuntu):

  WARNING: YOU ARE USING V4L DEMUXER WITH V4L2 DRIVERS!!!
  As the V4L1 compatibility layer is broken, this may not work.
  If you encounter any problems, use driver=v4l2 instead.
  Bugreports on driver=v4l with v4l2 drivers will be ignored.
