Hi all,

In certain bordercases, vobsub subtitles are incorrectly displayed
(mplayer) and hence incorrectly muxed/burned (mencoder) ; the corruption
seems to be limited to double-line subtitles.

This issue is present in all mplayer versions up to today ; tested with

The Avidemux2 project, whose vobsub RLE code seems to be based on
mplayer, exhibits the same problem, be it in a different way (interlaced
double-line subtitles).

To the contrary, both VLC and HandBrake handle these vobsub's without error.

For a minimalistic .sub/.idx set exposing the problem, and appropriate
screenshots, I gladly refer to bugzilla entry #1478
