Could be done, but I prefer to have a simple and clean interface...
According to the API spec for VIDEO_STILLPICTURE, 'the input data shall
contain an I-frame. If the pointer is NULL, then the current displayed
still picture is blanked.'

Well, this doesn't explicitly state that there *must* be a I-frame
header, but there is no hint that a I-frame without header might
be sent. Maybe it was an attempt to implement the NULL pointer
part of the spec, but this will probably not work (not tested).

I'll take this issue to the dvb mailing list. But first we should have
a solution which makes vdr happy. ;-)
