G450 DualHead Mode and Quicktime 5

[stamuraca]

Hello,

I just installed Quicktime 5.1 on my Windows 2K workstation. I'm running a G450 card in DualHead Multi-display mode, using "separate resolutions and color palettes for both displays."

The problem I'm having is my primary monitor begins to flicker when Quicktime is launched, and I lose the mouse arrow. The flicker continues until the Quicktime "splash" video finishes. The mouse never comes back. If I drag the Quicktime app to the secondary monitor, the app essentially becomes invisible, even though the buttons are still clickable.

I tried adjusting both monitors to the lowest resolutions and refresh frequencies, to no avail. When I turned off DualHead, Quicktime ran without problems. When DualHead is run using the "same resolution and color palette for both displays" Quicktime runs perfectly.

I'm guessing someone in this community has run across this problem before. Any advice?

Ran into that problem also on my Dual Head G400Max. After trying countless drivers and reboots, I found that the issue can be resolved in the Quicktime Settings control panel. Go to the Video Settings and uncheck the 'Enable DirectDraw On Secondary Monitor' option. Not quite sure what it does though. However, QuickTime videos play just fine on my second monitor using Win2K to manage the dual monitor capabilities. I haven't enabled the Dual Head since I have two physical cards installed. Hope this helps.
