I have a Samsung 900NF CRT and a Sumsung 191T LCD. Looking at both, I would have to say that they are both great for DVDs, of course the 900NF is better for gaming but the 191T is not bad, just the native resolution thing.
Ghosting and trailing are 2 completely different things, ghosting can be seen on still objects... even on crts. Trailing is what I think most people are talking about. DVDs on my 191t ,no trailing... games, some trailing, but tolerable. The picture is a lot nicer on the lcd imo, but computer displays are so much higher res than TVs that you just notice more good AND bad image qualities.
