You are wrong!
The first:
"The coded video rate is limited to 1.862 Mbit/sec." If you will go further at the same bit rates MPEG-2 quality will be much better, so as I already said it is totally useless to make higher resolution in MPEG-1 streams.
The second:
Sorenson is based on MPEG-4 technology and mostly aimed for QuickTime encoding, not for MPEG-1.
And the last thing:
I was asking about the possibility to buy DVD MPEG-2 (MPEG-4) quality videos at the price of MPEG-1. So as I see nobody is interested in it.
It looks like you are totally newbie to video encoding
