I have figured out how to enable Component out on nVidia Cards.  Im going to right a How-to soon on fedora forum but in the mean time here is the basic install.
Install the nvidia drivers 
add this to the Screen section of your monitor...
Option     "UseEDID" "FALSE"Option     "ConnectedMonitor" "TV"Option     "TvOutFormat" "Component"
#------------480p Group-----------------------------
#Option     "TVStandard" "HD480p"#Option     "metamodes" "CRT: 720x480 +0+0"
#------------720p Group-----------------------------
Option     "TVStandard" "HD720p"Option     "metamodes" "CRT: 1280x720 +0+0" 
#------------1080i Group-----------------------------
#Option     "metamodes" "CRT: 1920x1080 +0+0" #Option     "TVStandard" "HD1080i" 
Option      "AddARGBGLXVisuals" "True"SubSection  "Display"      Depth     24      Modes    "720x480" "1280x720" "1920x1018"EndSubSection
To select the resolution (480p, 720p, or 1080i) uncomment that group of options.  Only have one group uncommented at a time.  For me all modes work great!  This was a huge pain for me to figure out but after many hours of reading and testing there you go!.
Giving back to the MythTV/Linux community...
