DR4810 and DVD-R discs




I’m having a problem when recording onto DVD-R discs. I believe I should be able to record at different times until the whole disc is full. The disc should then be finalised to allow play back on other DVD players.

My trouble is that after I have recorded something onto disc direct from a camcorder (even just a few minutes) the menu list shows the title with the correct amount of recorded time, but 0 minutes free. So I cannot record any more than once onto any DVD-R disc. This has happened on 3 different discs from 2 different manufacturers.

It could be that I am doing something very stupid, but after repeated reading of the manual (great fun that was too!) I still can’t find out what I’m doing wrong.
Any help would be greatly appreciated.
