Thanks, I'll give it a try.  It looks like MPlayer isn't compiling right
now, so maybe I'll wait until tomorrow when hopefully the problems have
been fixed.

This is the error I get, just in case it helps:

ffmpge/libavformat/libavformat.a(allformats.o):allformats.c:(.text
+0xe84): undefined reference to 'ff_librtmp_protocol'
