Hi, there is a quite serious bug when using AC3 on AltiVec systems. Any AC3 audio file (and DVDs) crashes MPlayer at end of file or when exiting manually with messages like *** glibc detected *** free(): invalid pointer: 0x1076f3f8 *** The problem goes away when I recompile with --disable-altivec. Backtrace below.
