[MPlayer-users] svn revision question

[Giacomo Comes]

Hi,
I have found a bug in MPlayer and I'm trying to track down when the bug was
introduced.
I do: 
svn update -r "{date}"
in order to retrive a specific revision. It works for mplayer, but libavcodec and 
the other external libraries are always retrived with the last revision.

How can I proceed in order to have the same revision for mplayer and the extrernal 
libraries?

Giacomo
