In the HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run keys, you'll see two autorun entries that the dc3000 puts into the registry. One of them is the C:\Program Files\HP DVD\Umbrella\DVDBitSet.exe /NOUI and the other is C:\Program Files\HP DVD\Umbrella\DVDTray.exe. The programs in this entry are intended to autorun on starup. The DVDBitSet.exe program changes the bit setting on the DVD drive so that +RW disks are more compatible with existing DVD players. The DVDTray.exe program runs continously in the background. It is the program that reacts to the pushbutton on the dc3000 that launches the HP Video Transfer Wizard and also checks for firmware updates for your HP DVD drive. In some cases where there are other HP programs on the computer installed in a C:\Program Files\HP\... folder, there have been bug reports where an HP folder such as 'hpcoretech' is launching and staying on the desktop during bootup. You may also notice the DVDTray.exe isn't running in the background, which means that the pushbutton on the top of the dc3000 doesn't work. This problem can be fixed by adding quotes around these entries using regedit. Please note that the DVDBitSet.exe key has the quotes around the path to the filename, but the parameter /NOUI is outside of the quotes. A registry patch has been made available called RunRegistryPatch.exe that will do this for you automatically if you are uncomfortable with editing the registry. You can download it here.
After the edit or running the registry patch the quotes around the two files mentioned above look like the following:
