MythTV in native 1080i mode? (maybe with a 7050PV)

I have a 1080p plasma TV that will accept 1080p on the HDMI
inputs, but 
only 1080i on the component input. If I connect a MythTV box
to the 
component input, the MythTV _must_ be configured in 1080i
mode.

Is it even possible for MythTV to run on a system with the
graphics card 
configured in the 1080i mode? I never used a computer with
the graphics 
card configured in an interlaced mode, so I have no idea how
that would 
work.

Assuming I will use a motherboard with an embedded GeForce
7050PV chip, 
will that chip accept the 1080i mode? If not, do you know
another 
GeForce chip that will work in that mode?

I am planning to use a DVI-to-component adapter between the
computer and 
the TV.

The system will play mostly cable, satellite and OTA
content, which is 
1080i, 720p and 480i. My only source of 1080p content at
this moment are 
Blu-Ray disks, which are already handled by a PS3 - so the
MythTV box 
will never have to play 1080p for the foreseeable future.

Florin,
	It can be done. I've never done it over a DVI to component
adapter, but
I have used a VGA to component adapter successfully in the
past. Be
aware, however, that you may get better results using the
1080p
connection and some sort of display switch, rather than
component. 

	This will allow you to deinterlace all the interlaced
content, as well
as preventing the annoying flicker that can be present in
many of the
themes when running on an interlaced display.
