Default Re: How to setup dual video overlay with Quadro NVS

I see...
So I can't set any attribute such as SATURATION. hmm... The movie seems not so good at all...:-(

hmm...I think the "nv" doesn't support dual head at least my system doesn't.
When I use the "nv" driver to play the movie, the gxvattr is left over video overlay. And I can only play "one" movie with "nv" driver. Perhaps the nv doesn't contain the feature as the "nvidia" driver does.

Is there a method to solve the problem or I should buy another card e.g. Matrox, ATi?

I am wondering Ati is best recent card that support all feature in XFree86? The "man radeon" mentions that information such as below:
DESCRIPTION
radeon is a XFree86 driver for ATI RADEON based video cards. It con-
tains full support for 8, 15, 16 and 24 bit pixel depths, dual-head
setup, flat panel, hardware 2D acceleration, hardware 3D acceleration
(except R300 cards), hardware cursor, XV extension, Xinerama extension.


Thanks...
