The TS->PES conversion is the same as the old AVPES conversion and it
is done either way whether you are using PES or TS for playback or
not. It is just the format that the is send via the debi interface and
is more restricted than normal PES. The only difference to AVPES is
that you don't need to change PES that have a certain size (<=2048
bytes). For larger PES you will also get a conversion. For smaller PES
you will waste some space. The problem with TS playback is the dvr
interface which won't allow you a nonblocking write because you can`t
give the device a feedback via the various kernel layers. This is a
relic of the Nokia API. If you would allow TS input via the video
device there should be no problem, but then you don't have the section
filter mechanism and would have to add calls for setting PIDs.
