wrong determination of length of ogg-files
For example, vlc says "6:21 minutes" where the true length would be "6:46 min.". I disabled ogg-support (keeping vorbis and theora enabled). Now file length is correct, files still can be played (video and audio), but sound starts about 1 sec. too late (I noticed it first when playing system sounds). I can reproduce it with vlc-2.0.1 and latest git.
I am running Gentoo, compiled everything myself with CFLAGS="-march=corei7-avx -O2 -pipe" with gcc-4.6.3.
