test copying wcw vs the world: failed

[wouz]

hey my 2nd test, copying a copy of vigilante 8, worked for about 50 %. I copied it with clonecd again, but when i try to play it, it doesnt work at all OR ir works but not good: it skips the intromovie, the sound is in snippets and its loading too long n stuff, so its not good.
- I burned it at a 4x speed, do i have to copy it on 2x?
- Does it matter what kind of cd u use where to copy it on? Cuz with copying audio cd's from mp3's a 74 min cd-r barely works on many cd players, but an 80 min cd-r is like a normal audio cd, it works about everywhere. (by the way can u use also cd-rw's?)
