If playback of a pre-recorded DVD video disc or video CD is
interrupted (using STOP h or OPEN/CLOSE J ), playback will
resume where it stopped after you reinsert the disc. This applies not
only to the current disc but also to the last 20 discs you played.
You can switch off this feature if you do not want it.
This line appears only if you insert a VCD.
Using this function, you can activate or deactivate the PBC menu

This function allows you to finalise DVD+R discs. If the disc has already
