The quality is excellent, at least from my perspective, playing both NTSC and PAL DVDs out to NTSC monitors.
As you mentioned, the source format is critical to the end result (Scala has some compilations which are straight dumps from video to DVD, and look it. While DBM has re-mastered older material for its DVD compilations, resulting in much cleaner results.)
I don't know how the conversion/creation of PAL material from U.S. products is done, so I can't account for any difference in quality.
