I have sense fixed a few issues and figured I would post resolution.

1) TV not displaying once the system finishes posting was a sync issue.
Just because I set the Video resolution to 640x480 does not mean that
the "monitor" type can be the refresh rate of my sexy 21" SAMSUNG....
aka.. to fix it .. .set the monitor type to generic CRT at 60hrz refresh

2) Issue with Video card and display pallet was resolved via install of
native NVIDA driver ( PS My original post was confusing as the Video
card is not ATI .. wrong computer... wrong bug posting...sorry for
confusion) The NVidia driver was a bit of a pain as I had to install
kernel-headers and kernel-source via YUM and have it do a compile. After
a quick reboot..  all was well and things display fine.

Outstanding issue:
1) I have yet to get my "bunny ears" to work with my video capture card.
I boot up fine but when I go to play TV it has static. The manufactuer
of the card is ASUS but the chipset is a Conexant CX23880. How do I find
if this card supports "bunny ear style data"?  How do I enable the card
to receive this as an input? If this card does not allow "bunny ears"
... what card does with MythTV Support(so I can go purchase it)?

What is happening is that linux has *some* native support for tv out,  
but X needs to know about it. That's going to be card specific. Can't  
help much with ATI, but I'm sure someone here can. I use an nvidia,  
and there's just a few things I had to add to my /etc/X11/xorg.conf  
in the device section to tell it what type of display (ntsc vs. pal)  
and that is connected through svid. not near my myth, or I'd copy and  
paste the lines, but this is from wilsonet.com:

Section "Device"
Identifier  "Videocard0"
Driver      "nvidia"
VendorName  "Chaintech"
BoardName   "nVidia GeForce 4 MX 440"
#Option      "RenderAccel" "1"

# TV Out Setup
<----this is what I had to add
Option      "TVStandard" "NTSC-M"
Option      "TVOutFormat" "SVIDEO"
