Well, VDR sends the video frames and the OSD data to the driver. It expects
that data to be processed - what else can it expect? It would appear that
when the (Ralph's) driver/firmware receives only I-frames, it no longer processes any
of the OSD data. So at some point VDR just sits and waits until the OSD
data gets processed, before it can send the next block of OSD data.

So, the problem IMHO is most likely in the firmware.
