I hope your goal is to port the patch to 1.83?

Its 1.83. Try to post accurate info.

Always copy/paste commands you use, never retype. Such a command is 
rejected with "Unknown command: `r1_8_1'" so that's certainly not what 
you tried.

There may be an easier way, but this works:

mkdir tmp
cd tmp
cvs -z9 -d:pserver:anonymous at mplayerhq.hu:/cvsroot/ffmpeg co -l ffmpeg
cvs -z9 -d:pserver:anonymous at mplayerhq.hu:/cvsroot/ffmpeg co -r 1.81 

After that be *extremely* careful: the version of Makefile is somehow 
'locked' to 1.81, so if you remove Makefile and do cvs update you get 
1.81, not the latest! But since Makefile does not contain an ID string, 
its hard to know!
