And, here is the reply we've received from the EVO support folks.

------
The reason is in OpenGL version. You need at least v.1.5+ to be able to 
use the most recent ViEVO. As you can see from your logs, you have 3.3 
in case when you can successfully use it and 1.4 when you cannot. 
Perhaps RPMs are messed up. Please use drivers from nvidia web site, 
until SLC5 will resolve this issue.

Thanks again,
Devin

> Hi, All.  We have several SL5 systems using the proprietary nvidia driver from sl-contrib.  We did not have any trouble with these systems until we tried to view video in EVO (ViEVO).  We have no problem using EVO with the latest 260.19.29 drivers downloaded and installed from nvidia.com.  However, we are unable to view video when using nvidia-x11-drv from sl-contrib or nvidia-graphics260.19.21 from atrpms.  In all cases, xorg.conf is essentially unchanged.
