Well, the new P1.9 is out which supports both - and + formats at the same time, guess stahlbuerste is happy now
RICOH D01 is not listed within the supported media code list, but it wasnt for P.3.2 - however ala42 posted a list which he read directly from the firmware and RICOH D01 was there. Also Jan70 told me that RICOH D01 is supported. So it seems that the media code list published by Philips isn't complete. It also contained some false writing speed e.g. for SONY D11.
So maybe Ala42 can prepare such a nice list for us again
