DVB and Mplayer
Basically, you just need to generate a
channels.conf file (see this article) and place it inside
~/.mplayer/. Then run
mplayer dvb:// in a terminal window. You’ll get a video window appear, and the first channel within your
channels.conf file will start playing. To switch up and down between channels, you can press h and k. There’s a bunch of other helpful keyboard commands though not all of them will work with DVB.
While using Mplayer this way isn’t very user friendly, it may be helpful for some.
