Does this HWOTO work for all of guys on Januty or is there experiencing similar problems as I am, when using the libavcodec libavformat libavutil libs from ffmpeg-mt instead of the ones shipped with mplayer trunk?

If I am the only one having those troubles, then it might be something wrong on my end here...cuz I have basically just followed the HOWTO step-by-step and still getting these errors when compiling mplayer. I tried the previous and current svn revision of mplayer, but it fails on both

I appreciate any ideas...Thanks
