First like to thank everyone for helping to answer all the questions. These DVD recorders are bl**dy complicated!! I've had my machine for 2 months now and recently tried dubbing onto dvd-r. So far with little success - 2 successful attempts out of 6. Recorded Davinci Code in high speed mode and then used partial erase to edit it, used next feature so it was all done in one session. Put in blank disc and tried to dub in high speed. Failure message comes up!! So then dubbed in slow speed. The disc seemed fine, I then went to the finalise menu and again the disc failed. So disc was not finalised, re-tried with another blank disc, but went straight to slow dubbing mode, again at the finalising stage the disc failed . Very fed up. I then burnt another movie from the hdd to dvd-r and finalised with no problems! In slow recording mode as high speed dub was not on when this film was recorded This is very annoying. I've only had one success with high speed dub and then I only used partial erase twice to edit. I do like this machine but just too many irritating problems. When is the new model due as I'm now thinking about giving this one back and getting a credit note. Thank heavens for this forum. Its good for my blood pressure.
