Ah, I had similar "effects" once as well, after having the camera turned
on and off again several times. 

2 more things to check:

- I had a resolution with 640x480, your video is 1280x960. Either you
had toggled the [shunt] on, so that video goes through [scale_by] object
or you still have an older version than me (where the default in
#camera-help.pd is with upscaling, where in the really new svn checkout
the default is without).

- The video mode setting for the pseye I used when testing was 640x480
at 30fps (I guess it is videomode=1). Have you tried a different
setting?
