My old-fashioned analog TV died, and I want to buy a new flat screen TV. I watch a lot of old, TV programming on all the nostaglia channels like antenna TV, me-tv, etc. I also have a lot of old tv shows on DVD in my collection. I've tried watching some of these older, filmed shows on a new flat-screen tv, but they don't look as good as they do on the old-fashioned analog TV's. What should I take into consideration when buying a new flat-screen TV. Some of the terms I've seen are plasma and LCD, and dpi. I'll probably look at walmart or target or k-mart. My budget is approx. $200. Thanks!
