When I insert a dvd or an audiocd into my cdrom drive, and then doubleclick it, windows media player 9 starts, but it doesn't play the cds/dvds, only after I use the dropdown menu inside wmp and select the cd/dvd it starts to play it, but before I just needed to doubleclick the cdrom icon in windows explorer and wmp started and started playing right away. I checked the links and they are perfectly ok: Audiocd: E:\Programme\Windows Media Player\wmplayer.exe" /prefetch:3 /device:AudioCD "%L" DVD: "E:\Programme\Windows Media Player\wmplayer.exe" /prefetch:4 /device:DVD "%L" I also checked the autorun keys in the registry: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Cdrom AutoRun (set to 1 on my system) HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer (NoDriveTypeAutoRun) set to b1 00 00 00 on my system HKEY_USERS\.DEFAULT\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer (NoDriveTypeAutoRun) set to b1 00 00 00 on my system [HKEY_LOCAL_MACHINE\SOFTWARE\Classes\AudioCD\shell] @="" tried setting it to [HKEY_LOCAL_MACHINE\SOFTWARE\Classes\AudioCD\shell] @="play" (audiocd on), but doesn't help. So does anybody know how to tell WMP to play audiocds/dvds right away after I doubleclick the respective icons in windows explorer?
