Ok I 'll give it a try, although I'm not sure this will cure problem.
The main problem was, that the SPU data was not scaled along with the

scaling the the SPU data along, did not.
But I'll try to make the above changes as soon as I get home tonight.
Thanks for taking the time and looking into this matter.
