Thanks , I have added you
 

Thanks man , I will be waiting , thanks for patience and help ..

Problem solved by a fresh install of Windows 7 64 bit version.

New problem aroused: real media files play in active movie window
Old problem still existing: desktop mode not working

Both solved by using internal renderer overlay.

LE: ( subtitle messed up) problem back again after playing a file without subtitles (RMVB file)

it finally worked ..
 

I could finally find a solution for the very annoying problem . every one do this .... open your bs player window , right click preferences >> Subtitles >> Font ( in the primary subtitle window )
It will open new window , now u can see that the script is western change it to Arabic ..
Cant find Arabic , change the font type for certain types that has arabic script ( Ex : Arial , Arabic typesetting , ... ,etc ) then choose Arabic script and then TaDaa , it works ..
One more thing if it didnt work properly go to preferences >> Subtitles >> subtitle properties >> use new subtitle parser/ render , and unmark it , it should work then ..
If not , then burn your computer LOL ...

Apparently you didn't try arabic the first time?:tonguey:
Neither previously tried deselecting "Use new subtitle parser/renderer" as suggested in the post to which adicoto linked:
Anyhow, your problem seems solved now, so hooray!! :teeth:
But the bug seems still present :cry: as also mentioned by adicoto.
