Bug description:
  Binary package hint: cheese

  Ubuntu version: 10.04
  Cheese version: 2.30.1
  Hardware: Dell Latitude 2110 netbook - Intel Pinetrail CPU
  Settings: minimum resolution - 160x120

  Expected behavior: Start recording movie, recording starts promptly.

  Actual behavior:

  Screen is mostly frozen for ~14 seconds, and then recording appears to
  start tolerably.  Karmic's (2.28.1) performance was pretty poor, but
  the delay was around 4 seconds.

  To give the netbook a chance I set resolution to a minimum resolution.
  At higher resolutions, like 640x480, the machine just can't keep up at
  all.

  This has been observed on other hardware, and on a Core2Duo machine
  this startup performance is still very bad (though not quite so bad).
  Other apps, and gstreamer from the command line, do not seem to suffer
  the same problems.
