[mythtv-users] TV Out with STB Velocity 4400

[Donald McLennan]

There have been a few posts in the past (Jan - Can't get good signal to TV )  describing problems running mythtv to the TVOut on the STB Velocity 4400 card (16MB with TV).  I'm experimenting with this and am having some/similar configuration issues.  The funny thing is that when connected to our TV using the yellow RCA cable (composite) the video looks OK during linux boot.  The Fedora graphical login, the TV signal is not synced and the picture is rolling and sliced diagonal.  The rest of linux X does not display properly.
 
I've installed nvidia drivers 4363, per the groups recommendations. 
 
My XConfig file is below.  I've tried random settings on TVOverScan and RenderAccel.  I have not considered nvtv since this appears to work and looks like just some XConfig settings.  I've also tried with only the TV connected, both TV and monitor connected, etc.  
 
It looks like this is close to working.  Any suggestions on what I should change or try?  I appreciate your help - thank you,
Don
