I use 2 DVD players. A Panasonic S-97 which is a more expensive player, but can only play normal DVDs. And I use an H&B player which can play everything. It's funny when seeing that cheaper players support more formats, but of course you lose also quality, as the players are usually not the best ones. I compared the 2 with the same DVD, and the Panasonic one wins. Also it's connected via HDMI and 720p signal.

You should get a player for cheap, the new Samsung HD 870 is very cheap, around 80€, and seems to be a very good player, I already wanted to buy it, and exchange it with my H&B.

I only watch movies on the PC at work, I don't have a plasma there yet
