A/V-PES is a proprietary format of the DVB-cards. So they can easily
replay ... Other players simply don't understand that proprietary
PES-format, as it usually isn't used in any applications.

As far as I know, DVD-VOBs are PS, working with VDR and genindex. So it
shouldn't be a problem to replay it. I don't know much about
PS/PES-format, but if I remind well you're right with the additional
packets.

What I can remind, PS has additional information for syncing A/V, so
it's easier for the player to keep in sync.

It would also be a step to DVD-recording.

Does VDR use a own TS2PES-remuxer or do you use the one in the
DVB-driver? Then you could switch to the PS-remuxer in the driver.

Maybe someone with better knowledge of TS/PS/PES could give a comment or
create a patch?
