yes, this is correct, since the driver does not reconnect to a different
image size. instead the frames are still catpured at full resolution (pe
320x240) but only a part of it is read into the image-buffer (the lower
left corner of the picture).

what do you exactly mean by "when i leave pd" ?
actively leaving pd or being left by pd ?
on my system, pd crashes too when leaving it (pe: via file/quit). i do
not know the exact error-message, since it doesn't bother me (crashing
on leaving)
by the way, pd still crashes under linux when closing the gemwin - has
anybody similar problems.

does your capture card work correctly ? can you capture videoIN with the
standard hauppauge-applications ?

do no nothing
