It is also possible that there are problems with the USB driver and your main board. My adapter worked fine on my regular computer with a fully updated windows XP. On my epia however, the adapter didn't even get recognized after installing SP1 (even with the USB fix) 
Maybe you can opt for a clean install without updating windows and test if the DVD still freezes.
