Oh YEAH! That's the stuff! It plays now, and I see that it is better than VLC (first impression): the full screen mode doesn't pixelise the picture that much (very little actually) and it even plays perfectly the Ogg Vorbis files which VLC has a little trouble with.
Of course, I've only tried 2 files so far, but it kinda seems better.
Oh, and the step function with Ogg Vorbis files doesn't pixelise/merge/confuses/creates errors with mplayer.
Hmm, hmm. Now I'm a even more glad I upgraded to Panther
Just a question though: how do I select the subtitles on Ogg Vorbis files that have them (if I am at all capable of doing that)?
