Hi,

for DVB (digital video broadcasting) you could do that with the dvb-utils:

xzap -r <channel>
cat /dev/dvb/adapter0/dvr0 > recording.ts

You need a suitable channels.conf file (example files are included in the 
dvb-utils package) and you have to replace the x in xzap with t for dvb-t, s 
for dvb-s and c for dvb-c. The .ts stands for transport stream which is a 
special mpeg2 format (playable by xine or mplayer).

regards

Christoph
