partition file?

however I use Imagemagick, you can use it from the convert (1) program 
or directly from C++, Perl, and other languages. It uses mpeg2encoder, 
but can transparently take any kind of image as input. Remember to set 
the quality at the maximum level.

so you use the plain ioctl call from the DVB API, within vdr?

isn't this more or less the same work Klaus' routine already tries to do 
to emulate the not-working API call?
