Hi,
This patch makes the following modifications to softdevice plugin from CVS:
1. Some channels display white dots at the top and bottom of the screen due to WSS data encoded in the picture. This problem has been mentioned on vdr, linux-dvb and dxr3 mailinglists a few times. I added two new items in the softdevice menu that allow to cut off a number of lines from top and bottom of the picture. It is implemented now only for -vo vidix and dfb with i420/YV12 format and hardware alpha blending. ... -------------
I always wondered what this was on my DVB streams. Is there something similar in vdr-xine?

Well, in the case of vdr-xine, it's xine related, as xine has to deal with decoding the images. xine has the possibilty to do something like that (my patched expand post plugin makes use of it).
Just create a post video plugin that modifies crop_top / crop_bottom of each frame.
Bye.

Ok, done. Well, just for now (and as I have no idea how to do it otherwise..) I've extended the expand plugin.. Only, I havn't had a chance to test it yet. Can you *please* comment on the code?
What I'd really like to know is this: what actually are crop_top / crop_bottom? Are they the amount that is to be cropped in pixels, or are they amount which is going to be left visible? What would be an easy way to find out?
