I must TOTALLY disagree with the advice given above. If we followed a similar line of thinking about audio...we would be saying things like.....don't learn what high frequency distortion sounds like....ignorance is bliss!!! or don't even think about things like RFI/EMI .....and, by the way, you might as well buy a boom box instead of an audiophile system. Blah Blah Blah.
If you want to become a videophile, like you are an audiophile, don't listen to this hogwash. Instead, learn what Chroma Bug is....and then decide if it is worth it to you to get a DVD player without it. Incidentally, lots of reasonably priced players DO NOT have chroma bug.
When I finally learned what it was...and got a player without it....I found that my video experience IMPROVED quite a bit. Kinda like what we audiophiles find when we isolate a PROBLEM in our audio system and correct it. And it is not just the reds that improve.
Here's some great info on Chroma bug:

For those who want to remain ignorant...i suggest you NOT read it.
