Always had problem with subs

[pippop]

Hi this is my first post,let's start with a problem :oops:
I've always had problems with my subbed files since I installed bsplayer 0.86 ,the italic fonts ?? ?• Ä? ?? Ä? were not properly displayed so i used vob sub.
Now with a few ogg files containing italian subs,i decided to try bsplayer 1.00 build803 and a very strange thing appeared.....for the first 2-3 minutes the italic fonts were correctly displayed ,then the letters completely disappeared :!: .......this happens even with bsplayer version 0.86 but this time for the firs 2-3 minutes fonts are ok and then they turn into english fonts :!: :!: :!: (es. ?? become ?§)
What can i do?
