    I didn't see my own reply to the thread, maybe because it had an
    attachment.  Another easy way to panic the system is to open a
    second instance of the device, it will play for a couple of
    seconds and then panic, I've always been in X so I miss the error
    message.  I'm not sure what the best fix is, I mean, concurrent
    access at the device level is nice, but mutual exclusion will
    probably by much easier to implement.

    I have not heard of ktv.  I'll take a look tonight.  I made a
    little progress on mythtv, it now download the tv listings from
    schedules direct but the backend refuses to start-up the capture
    card.  I think I've located the problem to the some autoprobing of
    the cards inputs, I have some hacks that I will try tonight.

    I record to a file, and split every hour, I use a script to
    softlink the current file to a file called NOW.  I play using
    'tail -F NOW | mplayer -vf pp=lb -cache 5000 -'.  Or playing the
    file directly makes fastfowrard-rewind works, however, when
    playing a file directly it's exists at EOF instead of pausing like
    it does when reading from stdin.  I wonder how hard it would be
    hack that in...
    
    PVR-150 (and 250) interlace the video, so the de-interlacer is
    required for nice looking output.
