As Max suggested it could be a multipipe thing but I suspect
you may have a large managed area but a small video channel.
Performer is openning the window full screen but your video only shows
you the left or right hand portion of this. It will also be costing
you some performance due to the non viible fill.
Cheers,Angus.
