Red Line in middle of screen on Flash Video for Firefox

[Veritan_Kahn]

I have an issue where there is a bright red line vertically down the screen whenever I try to view a flash video. It is exactly in the center and is there whether I use full screen or not. I have a brand new computer so I don't have previous versions of Firefox or Flash Player. I am currently using Windows 7 (64 bit), Firefox 3.6.6, and Flash Player 10.1.

I have seen plenty of other issues talking about crashes and bad loads, etc., but I do not have any of those issues. Other than the red line, everything seems to play properly. I have tried uninstalling and reinstalling both Firefox and Flash, but no effect. I can view videos without any trouble through IE, so the problem seems to be with Firefox/Flash.

Any help/assistance would be much appreciated.

Thanks

Below is a screen shot of what it looks like.

Try to

• disable hardware acceleration (Flash Player Settings);
• update the device drivers for your graphics/video/display adapter.

Thanks for your report for flash player. Seems this is feature of ATI. refer to http://www.neoseeker.com/Articles/Hardware/Features/ati_9.11/2.html

Please disable Avivo demo mode and test it again.

Sweet! Thanks.

Disabling the demo worked.
