[linux-dvb] Record from DVB tuner

[shacky]

Hi.

I need to record some DVB channels from the command line using a
supported DVB tuner PCI card on Linux Debian.
I know I can tune the DVB adapter using dvbtools and record the raw
input using cat from /dev/dvb/adapter0, but what about recording two
or more different channels from the same multiplex?
How I can do this from the command line?
Could you help me please?

Thank you very much!
Bye.
