[MPlayer-users] mencoder subtitles expand problem

[jsuzuki at free.fr]

>From a DVD to a divx using the latest mencoder, I achieved placing the subtitles
in a black region below the picture using the -vf expand and -subalign 2
options.
The only problem is that subtitles "stick": that is the previous subtitle is not
erased when the new one comes up, which is especiallay annoying when a 2 line
subtitle is followed by a 1 line one.

Is there an option I forgot?

Thank you very much for your help,

John
