This is nice to know about so I'm sure many will make a note of it so it's appreciated.
In my case, what I am asking about is if there is a way to switch, using say the remote, between different resolutions.

In my case, for SD, I'm using a scan converter off of the VGA output into an RF modulator so I can pick up myth anywhere in the house on any TV by simply tuning in. So on the VGA output, I'd like to keep things at what was suggested to be composite size of 640x480 (which I thought was actually something else but that's the only reply I've seen).

When we want to sit in the living room and watch HD programs, we'll use the HDMI output that comes out of the nvidia card.

So my question is, will I need to switch between resolutions or will both devices be independent of each other? 
I've not yet connected an HDMI TV to the myth box.

 From what I've read, it looks like I could set up various resolutions in xorg.conf, then be able to switch between them using the remote later on. Each, the VGA and HDMI outputs would have their own settings based on what I'm connecting them to so I could just switch between settings while watching TV. 

Sorry if this sounds confusing, still new to myth so don't know all of the proper terminology yet.
