I'm not sure what you mean by native resolutions. Do you mean change the resolution depending on what you're watching? Is that possible in Myth? Even if that was possible, only CRT's support all native resolutions - all fixed pixel displays, such as your 30" LCD will do their own conversion, either up or down. I would suggest outputting at whatever your TV supports, which sounds like it's probably 1280x720. I watch both SD and HD content useing my Radeon 9600 SE's DVI connection straight the the HDMI input. Resolution is set at 1280x720 (matches my TV) and all content gets scaled automatically by Myth. All signals looks great.
