I'm preparing the release on Saturday, but it does work for me. BTW I forgot to change my setting so I ended up recording raw tv data from the saa7134 card, filled the hard disk up in a day, 20GB for 30 mins. > I'm mulling about how to enable DMA audio for Radio listening, but the > existing tools (e.g., fm) don't do anything other than tune the frequency > on the TV Capture card.

But they are also scattered around in mplayer command line interface, at least, one for -ao and another for -tv.

We do need some nice and clear wiki pages, setting up the DMA audio for the saa7134 is not easy.
