So the next question is whether accepting picture_coding_type=0 as
I-Frame is a proper fix. To be precise: Since VDR depends on knowledge
of I-Frames, does picture_coding_type=0 guarantee that an I-Frame is
starting? Does this hold for ALL TV streams ALL over the world, not just
yours?

If any non-I-Frame starts with picture_coding_type=0, the editing
function won't be able to show an editing mark on an wrongly detected
I-Frame, recordings may start with an non-I-Frame although they're
supposed not to, and stuff like that.


Cheers,

Udo
