Hmmm... I seem to remember a CD cover proggie that can import the text from an .nfo file, but it was crap. Sadly, I can't remember it's name though... perhaps someone out there does?!
What I just do is have the CD cover proggie running and then open the .nfo with wordpad, cut and paste, and walla it's transferred without loosing the text formatting. I usually have to change the font and size of the text to make it fit though. It takes an extra step or two, but it works every time
