[MPlayer-dev-eng] Patch to skip 3dnow downmixes in liba52

[Stephen Davies]

Hi,

Attached is a trivial patch to stop liba52 using the buggy 3dnow downmix
routines.  This at least gets multichannel ac3 output working again for
AMD users until I or someone can fix the downmixes.

I didn't yet commit it - rather have your comments first.  But it does
seem a shame to do a new release with this still broken.

Steve
