Got it working now using 'Video timing method: RTC', but I still have
the same probs... I found out that using sound device 'ALSA:default'
does end with no sound and a lot of 'WriteAudio: buffer underrun' in the
log, while using '/dev/dsp' stumbles with the picture and logging the
same 'WriteAudio: buffer underrun', but it comes back to live after
about 2 seconds...
Any further idea?
