Ah thanks ... but shouldn't that be

        if (getenv("VIDEO"))
                videodev = getenv("VIDEO");
        if (getenv("AUDIO"))
                audiodev = getenv("AUDIO");

in other words

  <               videodev = getenv("AUDIO");

Great, this because in that case I have not break the PCM interface
of the firmware with the new autodetection of AC3/DTS/PCM.

I've hacked test_av_play in such way that one get:

    Freeze       by pressing `z'
    Stop         by pressing `s'
    Continue     by pressing `c'
    Start        by pressing `p'
    FastForward  by pressing `f'
    Mute         by pressing `m'
    UnMute       by pressing `u'
    SlowMotion   by pressing `l'
    Quit         by pressing `q'

my examples I've around (VDR and VOB samplers in VDR format) work all
together.  Even the (well) broken files for testing possible lockups
of the bitstreamout plugin.

Now we've to see if we all can use this firmware all the day.
