I have AV Master and i runing it on my PC without any problems. CPU Celeron 400 Mhz, and grafic adapter Matrox G200. Few days ago i got a new grafic adapter MSI GeForce MX2 32 SDRAM with TVOut. The new grafic card doesn't work with my MB /it was ChainTech 6BTM Intel 440 BX chipset/. I change my MB with other one ... Intel 440 ZX chipset. Anyway now when i try to enable PCI bus mastering for video display the massage appear because AV Master can't write directly to my grafic card memory and i have to put the newest drivers for my GeForce. So i alredy have the newest drivers. I think it is because of my Mother board or because of my new grafic adapter but I'll be so thankful of any other suggestions.
What exactly does the error message say?
Since you have installed AV Master on a new motherboard, you should check that there are no resource conflicts. AV Master should have its own IRQ between 9 and 15.

OK i check everything and i find that the problem doesn't come from mu new MB /by the way it is manifactured by Intel and has 440 LX chipset/ because i put my old video adapter back and everything runs properly.
Now here is the error massage:
"AV Master cannot address the linear frame buffer of your graphic board. A driver update of your graphic adapter could help... Please contact your graphic card vendor for driver update. Overlay will be turned off!"
The drivers are newest, so what's the problem 
I hope it's not insuperable.
