No, in the current form it would not be possible to put in the
driver. It takes too much buffer space and time to be feasible.

If the remuxer is implemented into vdr, there shouldn't be a problem
with all of the above. I will see how that could be done and maybe it
is possible to change something in the driver to avoid remuxing
altogether. I still don't know exactly why these problems occur in the
first place, but playing with the remuxer gave me some ideas.
