[mythtv-users] MAJOR problems with GF4 MX 440

[MythMaster]

Hello,

Been struggling with this for awhile.  Have a Geforce2 card which works
flawlessly, but would like to use my 8X MX440 as this is not a dedicated
mythbox.  Some major problems.. 

1.)  Just replacing the card without changing ANY setup options mythtv
(the actual TV watching) is INCREDIBLY pixilated when watching livetv. 
When there is any movement on the screen The screen turns into a
perfectly symetrical checkerboard.  Popping back in the old Gforce2 this
goes away.

2.)  Set to NTSC and with SVIDEO enabled in the config the screen is way
too dark and the reds are too red.  nv-tv-out has a colorfix option but
my chipset is unrecognized for the MX440.

All help greatly appreciated!

Thanks,
