There have been some improvements to gspca_main and gspca_pac207
recently, as well as pac207 specific improvements in libv4l2. 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
