So i downloaded mplayer090pre 8 and then i've modified the sources....

* Where can i find tremor sources for vorbis support ?
* Is there anything else i've to do before start compiling ?
I compile on my SL6000L with gcc2.95.1 cram fs (DEV_IMG1.3)

I see, most of softtware doesent run on sl6000l so...we have to
recompile.....
