yep.  the steps I use myself are:

; fetch the rev I want without including the externals
svn checkout -r "$REV" --ignore-externals \
	svn://svn.mplayerhq.hu/mplayer/trunk

; grab the date of that rev from the svn info output
DATE=`svn info trunk|sed -n '/^Last Changed Date/s/.*: \(.*\) (.*/\1/p'`

; fetch the externals using that date
svn checkout -r "{$DATE}" \
        svn://svn.mplayerhq.hu/ffmpeg/trunk/libavutil \
        svn://svn.mplayerhq.hu/ffmpeg/trunk/libavformat \
        svn://svn.mplayerhq.hu/ffmpeg/trunk/libavcodec \
        svn://svn.mplayerhq.hu/ffmpeg/trunk/libpostproc

if you don't care as much about any specific revision than a particular
date, just pass the same date to both checkouts and you should get what
you want.
