Your player should be able to say that.
(ex: in Kaffeine, right click on the player window and choose "Track infos".)

You can simply : cat /dev/dvb/adapterX/dvrX > file.ts
that can be played by most players.

cat /dev/dvb/adapterX/dvrX | ts2es > file.mp2

Or use an application that provides easy recording (e.g. Kaffeine)
