On a Windows Vista-based computer, you finish recording an optical disc, such as a CD-R, a CD-RW, a DVD-R, or a DVD-RW disc. To record the optical disc, you use the DVD-R/RW drive, and you select the mastered disc format. Then, you notice that the read speed of the drive is much slower than the expected speed. This slow read speed causes the Windows Vista operating system to take more time to copy files from the drive.

Note: If you use a built-in DVD drive, you must restart the operating system, or you must resume from hibernation, to reset to the default speed of the DVD drive. If you use an external DVD drive, you only have to restart the external DVD drive.

Consider the following scenario:

• You watch live TV or a DVD in Windows Media Center on a Windows Vista Home Premium-based computer or on a Windows Vista Ultimate-based computer.
• You pause the live TV program or the DVD.
• You use the Start menu, a sleep button on the keyboard, or a Windows Media Center remote control to put the computer to sleep.
• You wake the computer, and then you try to continue watching the live TV program or the DVD.

In this scenario, you can view the video part of the live TV program or of the DVD. However, you cannot hear the accompanying audio.

Consider the following scenario. On a Windows Vista-based computer, you right-click certain files that are saved on a disc. Then, you try to access a DVD-VR format DVD that was created by using a consumer electronics DVD recorder.

In this scenario, you cannot view the pop-up menu. Also, when you try to copy these files from the disc to the hard disk, you receive an error message that resembles the following error message:

An unexpected error is preventing the operation. Make a note of this error code, which might be useful if you get additional help to resolve this problem:

Error 0x80070570: The file or directory is corrupted and unreadable.

Therefore, you cannot read these files.

After you burn a DVD-R in Windows Vista, you may be unable to read from the disc. When you try to read the disc, you may receive an error message that resembles the following:

Drive_letter:\ is not accessible.
The disk structure is corrupted and unreadable

When this problem occurs, the disc properties may indicate that the disc contains no files and that the size of the disc is zero.

This problem occurs with specific models of DVD recordable drives. This problem is known to occur with the following models. However, the problem may also occur with other specific models.
