Hmm, and where can I tell DGA to use the _real_ frameaddress?

Err, i meant -noxv. No different whatsoever.
(Probably because i comment out the v4l module :)
Oh, something strange from the xawtv -v 1 output:
Through Xvideo it detects YUY2,YV12 and I420 scaling
modes. Than it goes off detecting lots of info and
finaly tries 3 video modes. The first 2 fail, since
the Zoran does not do planar modes (but has YUYV
which is not the same as YUY2?) And the last one
tries is RGB565? Where does that come from? The Xvideo
extention does not seem to support that mode...
(And what does the 'Xvideo: no usable video port found'
mean? The list below contains 2 '[ok]'s...)
