PS2 With Neo4, some Teething Problems, anyone help ?

[GAZUK23]

Problem 1:

I tried out:
PSX1 (PAL) Originals = No problems !
PSX1 (PAL) Back up's = No Problems !
PSX1 (NTSC) Originals = No Problems !
PSX2 (PAL) Originals = No Problems !

And I finaly tried

5 different PSX2 Back up's = 2 of them no Problems !

But the other 3 came out in Black and white !

Does that mean those 3 are NTSC Back up's ?

Problem 2:

When I use a Normal Scart Cable I have Sound but no picture !
So I used the other Scart type (Euro I think) The one with 3 Coloured cable's.
Then It worked ! Sound and Picture were fine !
Why Is this ?

And If I buy the Blaze Cable will it correct my Black and white
problem ?
But will I have a no Picture again and just sound ?

What do I do....What do I do ??????

(Hope all of the above makes sense)

PS: Any place with a list of the DVD and the CD Games (Purple/Silver) ?
