The 'Disc Manager' is an integrated database in the DVD Recorder that remembers all
recordings made by this DVD Recorder. This gives you a complete overview of your entire
video collection at the touch of a button. Moreover, the Disc Manager gives you quick and easy
access to every recording
which film was recorded on which disc and how many unrecorded minutes remain on the discs.
And: You can go automatically to the beginning of the selected recording and start playback.
You can store up to 999 discs on this DVD Recorder. The maximum
number of titles is more than 9000. Each disc can have a maximum of 49
titles.
Don't use a disc stored in the Disc Manager for recording on other
DVD Recorders. If you use a disc to record on another DVD Recorder,
then this disc will no longer be recognized by the Disc Manager. In this
case, delete the disc from the Disc Manager's memory and then add it
after it has been recorded.
If you want to add child-proof discs you need to enter the PIN code.
