Yes, you can do in vegas with a mask if the videos have exactly the same frames
The basic procedure would be to put the SD video on the top track, HD on the bottom track . Draw a mask (a box) using the event/pan crop tool around the text on the SD layer that you want to cover up corresponding on the HD track . You can think of it as a small box on the SD video "covering up" that section on the HD video
Vegas isn't that great at upscaling, you might want to read about avisynth upscaling techniques for better results and less jaggies/aliasing (but there is a bit of a learning curve) . You can use the the same technique or similar methods using masks or mattes entirely in avisynth or other editors as well.
VirtualDub works just fine in Win7. AviSynth script:
Overlay(src, ovr, 1344, 984)
Replace ImageSource() with the appropriate source filters for your videos. You'll probably need to fine tune it to get the position exact. You may also need to adjust colors, brightness, etc. and use an alpha mask to feather the edges.

I found out that the frames don't quite match (the HD version is a little sped up) so I didn't get a very good result in Vegas. I tried adjusting the two videos to match as close as possible but it still didn't work.
I also tried AviSynth and got a ton of script errors. Guess I'll just stick to blurring the watermark out
So they're "identical" but different? :0
They have the same content but the HD version has a faster playback rate so covering up the watermark is impossible.

No doubt they're different cuts too. Different ad breaks, etc. It's still possible to fix, just a lot more work.
