I just added an HDTV receiver to my HT setup which I intend to use for non-cable, over-the-air reception of local HDTV broadcasts. It has three video connections on the back: composite, s-video, and VGA. My HDTV-ready TV only has composite, s-video, and component video, so:

- For s-video, what is the rated resolution? Will it support 1080i? If not, what is the best resolution it will support?
- Will I be better off using the VGA output instead? If so, what type/brand of adapter should I use to convert the signal to component video?

Also, I have not yet purchased an antenna, but was considering the Radio Shack $49 model. Is there anything better out there I should consider?

Thanks in advance.
