at least for DVB-input, but also for DVB-output.
I remember you have linuxtv-1.0.x installed (or dvb-kernel, that works 
the same way),
but maybe you didn't install the drivers headers in the right place.

After having run
$ ./configure
config.log will tell you what went wrong; most likely you only have to 
copy dvb/*.h  in /usr/include/linux/

the above is  not the right way to encode from dvb, the row below is:
$ mencoder -of mpeg -oac copy -ovc copy -o file.mpg dvb://CHANNEL_NAME
where CHANNEL_NAME is specified in channels.conf

what version of mplayer? Maybe 1.0rc_something? -of mpeg is broken 
there, use the
last version from cvs.
You should also remember to load the module dvb-core with 
dvb_shutdown_timeout=0.
If you use mplayer from cvs you need that parameter, but few days ago I 
posted a patch
in this ML to remove that requisite:

It works well for me.

append to the command line:
 -endpos 00:00:10

DVB subtitles are not supported yet.
