joker97: or if you've been buying the right titles, your equipment is of the wrong type!
I have about 60 or so BD titles and about 30 HD-DVD(if people remember those now). I have been impressed with the PQ on all of them and of course some are better than others.
The other night I was playing Up on DVD (on an upscaling DVD player) going to my 1080P PJ on a 100" screen. It looked surprisingly good. Then I rented the BD and played that. What a difference! And of course added to that DTS HD Master audio versus the DD on the DVD.
My view is, all of your problems are equipment or setup related. If you can't see the difference between DVD and BD then you wasted your money with the gear and titles.
It would be interesting to see a list of titles you are not happy with.
