Install failed - allformats & libavformat error?

Hi, I get the below error, and then when I press enter to continue it does.. but then I get the following mplayer failure... I have git and svn installed... so not sure where to go from here...

Checked out revision 33248.

No FFmpeg checkout, press enter to download one with git or CTRL+C to abort

i click enter and then it says cloning into ffmpeg etc and goes from there and then when it gets to the mplayer it fails with the below:

make[1]: *** [allformats.o] Error 1
make[1]: Leaving directory `/usr/src/ffmpegscript/mplayer/ffmpeg/libavformat'
make: *** [ffmpeg/libavformat/libavformat.a] Error 2
cp: cannot create regular file `/usr/local/cpffmpeg/etc/mplayer/codecs.conf': No such file or directory

I am using the latest version 7 installer.

ideas???

Tks.
