Well, I will try to have a look at the sources, but probably, I won't be
able to patch it correctly, if the changes necessara are more than
absolutely basic and obvious...

I once compiled the tw68 driver for another card. And here the borders
were also not correct. In this driver it was very easy to find the
settings to change.

Thanks, you probably hinted me into the right direction. I use mplayer
to play the video stream and mplayer does indeed recognize a 640x480
video stream.

I am not using any crop settings for these tests. But maybe it is
possible to tell mplayer that the stream is 720x576 instead of the
640x480 it believes. That is, if the stream coming from the driver is
really not 640x480.
