No remote security camera viewing after 5 update

[MitchM]

Hello,

After upgrading from 4 to 5, I am no longer able to view my remote security cameras.
In Parallels 4, the problem was solved by having video.overlay_noflip=1 in the boot configuration window.
In Parallels 5, the same video.overlay....etc is in the Boot order/Boot flag box, and I am able to connect to the cameras, but all I get is a black screen.
My system is a MacPro quadcore, 6GB ram, Windows 7 VM

Any suggestions?

Thanks in advance,
Mitch
