Short answer: yes, it has same problem, and that patch has no conflict.
stream/udp.c has no change since r19550.


This is the first time that I report bug and it's patch to mplayer, so I
read
docs about bug reporting step for this project. I think, dev list is right
place to this case.

And I checked out HEAD of svn too, and see them. (just check with my
eyes, I'm lazy, have not compile and run them. until your mail.) Now,
I've check them by running.

In fact, I've search on this mailling list and user's mailling list for this
problem, and found a related topic about reuse socket opt.
maybe, `svn diff -r12799:12800` is root of this codes/problem.
