Wanrer Bros DVD's and Creative DVD ROM

This question relates to a previous post of mine asking why my DVD's skip when i play then inmy dvd rom drive.. and i happened to narrow the problem down to only WB movies skipping.. i havent quite figured anything out yet..but, not all WB movies skip...and when they do.. its a pretty major skip.. the movie doesnt lock up or anything.. but it just skips kind of badly.. even the sound skips.. so..does anyone know if WB encodes their DVD's a certain way or if they do something differnt to the disk.. because all of the movies I have watched that arent WB dont skip, and if they do its from the layer transition on dual layer format movies... so I really dont know what up with WB, and I doubt theyll tell me if they encode their movies differently..some stupid privac thing or whatever... if anyone has any idea respond to this post plz..thanx
