I've installed the nvidia 1.0-7676 driver using the install script  
provided here: http://www.nvidia.com/object/ 
linux_display_amd64_1.0-7676.html

Do you think this could be a matter of how I configured the driver?   
Should I try and load the driver through some other means, or is  
there a i686 driver that can be used on my x86_64 system?

Are there nvidia logs somewhere that might give a little more  
information?

And if it's a driver issue, why would I be able to watch live tv just  
fine through azap and mplayer but not mythtv.
Sorry if these questions should be obvious to me but I'm just not  
there yet.  Thanks so much for your input though.  I'll definitely  
search around driver related issues.
