Take furballi's advice and remove AnyDVD from your system and install the latest version. This eliminates the possibility of a bad install. Then either use enditall or in the start-run box type in msconfig.
In msconfig go to startup tab, record what exising progarms you have checked,then click on disable all and reboot. Now there are no programs running that could potentily conflict with your DVD burning and possibly cause problems. Windows needs none of those programs listed to work properly. When done burning go back into msconfig, check the boxes that were originally checked and reboot, your back to normal now. This process serves two purposes, eliminates possible software conflicts and frees up resources for those having lower amounts of memory installed in their computers.
May sound a bit inconvenient, but sure as hell beats coasters and scratching your head for hours as to why something is not working. The enditall program does this without the need to reboot each time, the choices are yours. This may or may not correct your problem, but you must start with the basics.
