I am in the market for a new DVD player since mine doesn't seem to be working. Obviously, since I am posting this on the budget board, I would like to get the most cost-effective player. I have read a lot about Blu-Ray Discs, but know nothing about them excpet that they are more expensive than "normal" DVD players. If I buy a normal DVD player, will it be obsolete within a year or two due to the emergence of Blue-Ray technology? Or will the "normal" DVD player still be "modern" technology for a number of years? Thanks!
