if you have windows..go to microsoft web site..and look for the program you have..XP or windows 7, and do a check for updates. they also have a message board i believe.
or click on:
"Start"
"control panel"
"system properties"
"hardware"
"drivers"
'windows update"
try that. someone with more experience than me, will be long to help you..it is probably the program you are using to view the dvd/cd. need to updte or download another progrm/media player to view it.
