Yes, it does allow you to stretch those modes. Maybe I phrased my comment above poorly, but to clarify, I have the SA8000HD box set to output 1080i and 480i. When I've got a channel displaying HD, I don't expect it to allow stretching. When I'm watching a non-HD channel though, if I press the "PIC SIZE" button on my Toshiba's remote, it displays "Not available" on the screen. That implies that it's receiving 720p or 1080i (page 30 of my owner's manual). I can use the "#" button on the 8000HD's remote to cycle between sidebar, zoom, and stretch though.
The button in the lower-left, "Input Source", I believe, also does this. I'd rather use, or at least try, the Toshiba's scalar to see which does a better job.
A few things from my Toshiba's manual:
Viewing the wide-screen picture formats
(480i and 480p signals only)
The PICTURE SIZE feature is not available for some program formats (such as 1080i and 720p). Such formats will display in Natural picture size.
