This is a very good point - and, even though I suspect from knownalien's post that he's already aware of this truth, it's still worth pointing out in general. No player (standard DVD, HD-DVD, or Blu-ray) or standalone video scaler can take a DVD and produce a true HD quality image. Even the best scaling approaches are also going to be dependent to some degree on the quality of the DVD transfer - a really good transfer can yield some really impressive upscaled results, even if it doesn't directly equal true high-def.
