Be carefull not to drink too much. Your

It's in archives somewhere, unfortunaltely i'm unable to get
url/topic/whatever now. But the problem is very easy (iirc it was you 
who explained to me what's wrong :)) - some encodes with
softsubs in them do not put " " line when the text should disappear.
They only set duration of previous text.
Normally subs should look like that:

timestamp | "text"  | duration (or maybe start-stop timestamps)
---------------------------
X         | "blah"  | Y
X + Y     | " "     | Z
X + Y + Z | "blah2" | A

In this broken encodes there is no " " sub.
mplayer should use duration but it does't - so the "blah" sub 
is displayed till next sub ("blah2") "occurs". 
In case of valid not-broken encodes mplayer displays " " sub which
erases previos sub and everything is ok.


Sorry for probably not precise explanation.
