iTunes 7 Problem fixed

Right, found the fix for the error I was getting, got to ensure your sound card hardware acceleration is full. So:

Start -> Control Panel -> Sounds & Audio Devices -> Volume tab -> Speaker Settings -> Advanced -> Performance

There set it to full.

For DirectX:
Start -> Run -> dxdiag -> Audio

Again set it to full.

(I had to do it for both, so I would check both)

Enjoy
