/* Using the VIDEO_STILLPICTURE ioctl call would be the
correct way to display a still frame, but unfortunately this
doesn't work with frames from VDR. So let's do pretty much the
same here as in DVB/driver/dvb.c's play_iframe() - I have absolutely
no idea why it works this way, but doesn't work with VIDEO_STILLPICTURE.
If anybody ever finds out what could be changed so that VIDEO_STILLPICTURE
could be used, please let me know!

2003-08-30: apparently the driver can't handle PES data, so Oliver Endriss
<o.endriss@gmx.de> has changed this to strip all PES headers
and send pure ES data to the driver. Seems to work just fine!
Let's drop the VIDEO_STILLPICTURE_WORKS_WITH_VDR_FRAMES stuff
once this has proven to work in all cases.
