DVD Loader help please.

[Distearth2]

using Swap Magic to boot Conflict Vietnam goes to a black screen and stops DDR Latest one boots to black sreen with a little swirling thing in the bottom right
Using SM DVD -> DVD Loader 5v3 no (something) -> SM DVD -> DVDR PS2 CV game boots to a black sreen same as with just Swap Magic by its self same with DDR seems loader doesn't change anything. Other games work fine with SM I thought DVD Loader was to fix these problems am I doing it wrong is there a How to for DVD loader?
Thanks for any help and please don't just tell me to get another Mod... that really doesn't help.
