I have a Samsung HD-841. It is junk. I have the video through DVI and I am going to try it through component video. I didn't notice how weak this unit was until I put it on a 48" Mits HDTV.
Any dark tones look absolutely terrible; starts to get blotchy and blocky. Sound is good (after I figured out I had PCM selected instead of bitstream, just a wee bit difference

)
I watch HDTV HBO movies, talk about spoiled. They look incredible. Then I turn the Samsung DVD player on and cringe at the visual artifacting.
Put me out of my misery. Suggest a DVD player that is similar in features for a similar price (<$200) that doesn't have the same picture quality as a Barbie DVD player (if there is such a thing). Thanks.
