What's wrong with "Subversion snapshot" (or "source snapshot") if you don't want
to use svn?
(These are the only supported versions of MPlayer.)

This command does not do what you expect, if you think the message shown
(actually shouted) is not clear, please make a suggestion how we can improve it.
If you want to record from dvb, use
mplayer dvb;//120 -dumpstream
If mplayer dvb://120 (or mplayer stream.dump after above) does not show video,
your problem is likely that PMT is missing from channels.conf.
(Ignore the following if you wanted to record a DVB audio stream.)
To fix it, run mplayer dvb://120 and let it play audio.
Now run scan -c in another console, in my case that shows:
0x0000 0x2775: pmt_pid 0x0065 ORF -- ORF1 (running)
ORF1 (0x2775) 01: PCR == V V 0x03f2 A 0x03f3 (ger) TT 0x03f7 AC3 0x03f5
The relevant line in ~/.mplayer/channels.conf is now:
ORF1:INVERSION ... ... :HIERARCHY_...:1010+101+1015:1011+1012+1013:10101
(Note the 101 = 0x65 pmt_pid, you may have to run scan several times to get a
pid != 0)
