I am unable to find the original Mplayer with the necessary libraries. Can someone point me in the right direction?

I am also in need of the correct ipkg update feed.

EDIT: It might be important to know that i'm running pdaxrom 1.10r198 on a c1000.

You want mplayer-bvdd-iwmmxt. You can't use the bvdd part with r198, but the other optimizations will make it perform better than any otehr mplayer out there.
