I think I understand your question now. You want a 4:3 picture to be upscaled to 1080i and then stretched (change in aspect ratio) to 16:9. The 606 should be upscaling fine, but I'm not sure if it is capable of changing the aspect ratio of a HD picture.

Your TV is not capable of changing a HD aspect ratio though:
