Random programmer´s notes on hacks in the source code:

* /apps/cupid/gst/video_emumode (gconf) can be used to force or disable
   interface emulation of the XOverlay interface (0 = auto, 1 = forced
   emulation, 2 = disable emulation).
* for video sources in src/gst/list.[ch], the GObject data pointer
   "template" contains the video template found during probing. After the
   initial probing, probing is disabled and devices such as webcams will
   claim to support any media type, which is obviously not true. This is
   done for speed (probing takes long).
* if DV doesn´t work after turning on the cam, reconnect the plug in
   the firewire-socket. Switch to another input (or None) in preferences
   and re-select DV, now it'll work.
* for tv/cards and overlay, you need to load the v4l/Xv module in xorg.conf.
