Yes, indeed. You have to use multiple programs in combination with the
duplicate module.
When you use the option "--sout-all" the stream will contain all
channels to given frequency.
I am sometimes using a command line like:
vlc -vvv --programs=1025,1026 --color --ttl 12 \
--ts-es-id-pid dvb:// --dvb-frequency=714167000 \
--dvb-adapter=0 --dvb-bandwidth=8 \
--sout="#standard{mux=ps,dst=$FILE_NAME,access=file}"
to record two programs (in the same multiplex) into one file and then
when playing the file with VLC, I can select the different audio and
video tracks for each program. One could also combine the duplicate
module and this to record into different files. There are a lot of
possibilities but you have to experience a bit because the
VLC-Documentation does not cover all possible combinations of the things
you can do.
I am not 100% sure but I believe that in the case of my card (AVerTV USB
A800) the Windows software is not able to let you watch or record more
than one channel per multiplex and VLC for Windows does not have dvb
support (due to special drivers for each card, I believe).
