Gents, I can compile mplayer on centos 4.5 AMD 64 in native 64 bit mode and it plays the dvd, and also compile for 32 bit mode "gcc -m32" on it also plays the dvd. "mplayer dvd://1". I can compile mplayer on centos 5 AMD 64 in native 64 bit mode and it plays the dvd. However, when I compile in 32 bit on AMD 64 centos 5 I cannot play the dvd. I get: Playing dvd://1 File not found: '1' Failed to open dvd://1 My configure string is: ./configure --disable-ivtv --enable-largefiles --target=athlon_xp --cc="gcc -m32" --as="as -32" --with-extralibdir=/usr/lib; make; make install I need the 32 bit mode as it will then play wmv's. Has anyone done a 32bit compile on centos 5 AMD 64? Can you play dvd's? If so can you share how you accomplished this. I am thinking this more a centos 5 issue than an mplayer issue. This is why I posted here. THanks, Jerry
