DVD playback trouble

[shorto]

Hi all!
Well my problem is a little strange. I can play some DVD's without a problem, but the picture is strange, I mean i had better quality picture while I had cable TV, than i have on most DVD's. Here's a screenshot of my new official StarGate DVD's that I ordered and as you can see when I go full screen the image is horrible and I really don't believe that original DVD's are supposed to have such bad quality.

Now the other problem is, that some DVD's don't have sound. I don't know why, they only work in VLC media player and nowhere else.

And since everything works in VLC media player (well the picture is still horrible, but the sound works) I believe that this is some sort of a codec problem, but I'm stumped I just reinstalled Windows and the only thing that I didn't install is PowerDVD since the software collides with my TV Tuner software and then my TV Tuner doesn't work could that be it? Please assist.

Bye

Don't know about you ,but it looks fine to me, how does it play on standalone? you sure it's an original or copy? VLC is what I normally use for viewing on PC.....hard to tell from one frame.....
What TV tuner SW collides with PowerDVD? I have GBPVR and PowerDVD w/o probs.....

It's the original copy 100% I bought it in the oficial onlinbe store. The video plays with a normal quality on the standalone player and on ps2.

If it plays fine with normal quality on the standalone then AFAIK you're good to go then....enjoy it!! 8)
