[mythtv-users] Video quality on 0.28 worse than it was on 0.21

I don't think the nvidia drivers are getting loaded and I can't figure out
how to get them used.  I uninstalled them and installed them using the
Other Drivers section and still I get this:

*allen at MythNew:~$ lsmod | grep video*
*video                  40960  1 nouveau*
*allen at MythNew:~$ lsmod | grep nvidia*
*allen at MythNew:~$*
allen at MythNew:~$ lsmod | grep NVIDIA
allen at MythNew:~$


I know the board is recognized

*allen at MythNew:~$ lspci | egrep -i nvidia*
*01:00.0 VGA compatible controller: NVIDIA Corporation NV44 [GeForce 6200
LE] (rev a1)*

Google is good at showing me others who had this problem but not at a
solution that I can use. Most suggest using commands that I don't have.

Anyone?

Allen
