ehm, why do a conversion?
a ts can be generated by selecting pids of a service
with demux.output = DMX_OUT_TS_TAP
after adding the pids, just read and save the content of
the dvr device.
i think choosing PES as a storing format - causing incompatibilities with different playback solutions than vdr -
was made, because the av7110 full featured dvb adapters are not able to
act like normal set-top-box chips. they are not able to playback from a ts file directly.
so internally the ts is converted and repacked by the driver. as these functions have got some race conditions
that are not fixed (will they ever be?), imho there is no real chance to have ts in future.
