[MPlayer-users] why a mplayer short video instance waits other long video instance to complete?

[actr.d]

Hello,

I will try to explain my problem. :)

I try to develop a Delphi app.

There are a number of lists. 
Each list contain some threads, each thread resume its next thread ....like linked list.

some threads play videos via mPlayer in seperate process slave mode and the thread wait the process to complete (not STILL_ACTIVE)

if first thread in two or more threadList is mPlayer then short videos stops but they dont resume their very next thread.
They wait long video after that continue normally.

if first threads are not call mPlayer ther is no problem. They follow each other regularly...

I need any idea , or clue ...

I hope i express my problem a bit...

Thanks.
