Are you using the latest v4l-dvb and libv4l2? I get some slowdown halfway when using capture-example.c and it seems to improve when I use the latest v4l-dvb and libv4l2 from mercurial. http://linuxtv.org/hg/v4l-dvb Sean bifferos wrote: > Hi all, > > Can anyone give any clue as to why I might get this error > when capturing from a PAC207 webcam?
