AV_PES was a proprietary, non standard format, so changing that was certainly
right. PES on the other hand is AFAIK the recommended format for _storing_
recordings, while TS is the format for _broadcasting_.

Changing VDR's recording format to TS is not going to happen.
I would be willing to change the replay functionality so that it
sends video and audio data into separate devices (see my other post in this
thread). This would most likely be a step in the right direction.

Maybe the problems some software players are having is as simple as
some missing or "not as expected" headers in the PES data? If somebody
can come up with some fine tuning here, that could be done.
