[xine-devel] dvd branch seg faults with mediaLib

[Robin K. <kom...@my...>]

There's a bug in the dvd branch that stops it from working with Sun mediaLib.
In any case, isn't the dvd branch based on 0.9.6 which works fairly well
anyway? I don't have the time nor heart to try anything else today ~_~.
