It's kind of cool to see that this issue, whilst not fully resolved, per se, has been adressed. There is an answer, just not a very pleasant one...
As for me, myself. I am truly gobsmacked that people would play this game in SD! Are there people here who have not seen a kroagn, or Garrus, in HD?

I hope not to encur the wrath of SDTV owners.

But if I may offer an idea/solution, consider buying the
Official Xbox 360 VGA Cable and use your Xbox 360 on the computer monitor you are using to access this website. (If you are indeed accessing this site from your home and not your library, etc. etc.)
If your PC setup is decent and you can use your PC comfortably, I think it'd be worth a shot. If you happen to have a Widescreen computer moitor. Then I think you should seriously consider it.
This is the set-up I use and it has worked really, really well.

If it's a little technical for you, there are plenty of forums and tutorials to help get you started. I wont go into uber long technical details now, but if this IS something you choose and cannot google yourself some easy answers, I'd be happy for folks to PM me.
I know spending more money doesn't sound like a good idea right now and you're probably angry... But $40 USD is a cheaper than an HDTV and a lot cheaper than a decent HDTV. And if you're going to purchase a new lead to fix this text issue, why not purchase a lead that will give you a HD image too? The Mass Effect universe is a gorgeous one and you're missing more than text when you play this game in SD.
