[mythtv-users] eVGA HDTV-7 interface?

[Johnny Russ]

I can pick up an eVGA 7300GT for $15 after rebate on Amazon 
(http://www.amazon.com/EVGA-e-GeForce-7300GT-PCIe-Video/dp/tech-data/B000G69AYU/ref=de_a_smtd). 
I was thinking about getting it but I was curious about the HDTV-7 
output listed in the specs. I searched around and can't find any good 
explanation about HDTV-7. Is this the component out that some people 
have mentioned with other cards on this list? Also before I buy does 
anybody have reason why this would or wouldn't be a good card for a myth 
box? I am currently SD only but plan to move up to HD with this box in 
the future.
