You can crunch video with MPEG2 soft or hard. Lots of options available; lots of parameters to tweak. And even then, all mpeg codecs are not created equal.
But you need to learn about GOPs and bitrates. Whatever preset you are using is probably going to be set at long-GOP (anything greater than I-frame) and a bitrate suitable for DVD. Dunno what options yr software has or how customizable the output options are. And sorry, my knowledge is more general than specific as to what bitrate would be advisable.
As to visual loss, you want to stay far away from it. You want to retain as much quality as you possibly can (see post on generation loss). By definition, MPEG is a lossy codec. I'd classify Cineform/Canopus HQ/Prores as less-lossy. See Codec - Wikipedia, the free encyclopedia
Also, since you're goal is color correction, the codec color space is very important. Generic (DVD) MPEG is a limited color format. Greater color encoding is part of the MPEG spec but may not be available with the codec you are using.
How about this: export a short section with your MPEG2 settings and the same with, say, uncompressed if it is an option. Bring it to the mac, mess with it and then bring it back to your pc. And then go ahead and downconvert and burn to a DVD and see what the final result is. Really no substitute for trial and error.
