I made the changes in the registry as advised but sadly I'm still having problems in getting it all to work, it does play but only after average 40 seconds delay.

Have you try to increase IRPStackSize (the max is 50) and SizReqBuf further?

So edit the registry again? if so what values should I try? thanks mate, appreciate you looking into this!

Any value below the max values, and max values are listed at the end in (xxxx)......
