Consider the following scenario. On a Windows Vista-based computer, you insert a writeable DVD into the computer's DVD drive, and then you click Burn files to disc. Next, you click Show formatting options in the Burn a Disc dialog box, and then you click Mastered to burn the DVD by using the Mastered format. In this scenario, incorrect recording speeds are displayed in the Recording speed list in the Burn to Disc dialog box.

For example, if the DVD drive supports an 8x recording speed, Windows Vista displays 3x, 3x, 2x, 1x, and 1x in the Recording speed list. Therefore, you cannot select the correct recording speed for the DVD drive.

This problem occurs because Windows Vista rounds the recording speeds that are supported by the computer's DVD drive to the nearest whole number.
