I view almost all SD content, but have a 16:9 TV.  I've been happy with the 16:9 Stretch that MythTV provides for - but am always up for something better.  As for the US, there is HD content available, but its not the majority for sure.

I would love to see this in MythTV, but I guess it would depend on how soon HD is coming to the area that a developer who is capable of developing this.
