Laton,
Buy a Blu-Ray player. They make dvds look absolutely fantastic. They sound really really good with cds and dvds. And you can play Blu-Rays, which are fantastic. Going to be lots of Blu-Rays, getting cheaper and cheaper all the time.
I have two Sony Blu-Ray players, one that used to be their top of the line, the first one in the ES series, and a midline one bought last year, for about 300 bucks, both totally problem free, totally enjoyable.
