i have a Question
 

hi, i am a new user of BSplayer, i noticed a problem; while i was playing a movie i found that the picture is upside down and i coudn't find the correct option to fix this problem.
please send me your recommendations.

Probably it depends on the filter used to decode your video.
Some of them (XviD, FFDShow, etc.) have options to flip video vertically..

Maybe do a search on the forum for "upside down", there are many questions and answers related to this problem..
