Hi,
this might interest you.
I didn't look at the v4l code of the DVB driver myself, yet.
Example: buffer.pitch = 1440, buffer.width = 200

Modified files:
interfaces/IDirectFBVideoProvider: idirectfbvideoprovider_v4l.c
Log message:
Work around a bug in the DVB kernel driver (more likely) or the DVB hardware.
When using buffers with a pitch much higher than the width suggests (e.g. using
DSCAPS_STATIC_ALLOC and downsizing), the lower part of the video is cut off.
- b.width = surface->width;
+ b.width = buffer->video.pitch / ((bpp + 7) / 8);
