Help pls - Error - while watching BS on TV

[offf]

I have a strange problem with BSplayer, hope i can explain it..

I created a virtual monitor in my PC, i mean i created 2 monitors (one real, one virtual) I connected TV to my PC, and TV shows me the virtual monitor which is on the right of my desktop.

While watching film, i carry BS, on my virtual monitor to watch it from TV. but when i do this BS gives me error frequently, i can say an error in aproximate half an hour.

but when i watch the film on my desktop everything is ok and no problem occurs..

How can i stop giving errors while I'm watching TV with BS? hope i could explain my problem and hope there is a solution.
