OSD and images

[Matjaz Thaler <matjaz.thaler@rd.iskraemeco.si>]

Hi,

I would like to implement DVD subtitles on DVBs card
but I have problems with displaying images. Image larger
than 400x18 pixels hangs the driver. I tested with attached
software and driver version 0.05.
Any idea how to solve this problem?
