You can possibly add me to this list. I have the DVDR985A03 with firmware version FF12j with a manu date of March 2003, purchase in/on about May 2003. It has worked fine for me with the exception a few coaster early on. It is not used very extensively, just to time shift WB and UPN from Dish Network and to archive the occasional show off my DirecTV DVR.
Anyway, recently it has started to not recognize blank +R discs or previously recorded ones for that matter. It is still playing DVDs and +RWs. I do not get any error code other than the NO DISC message.
I'm not sure what the latest firmware version is or whether I want to attempt an upgrade. I downloaded the latest version from the Philips website. The site said v6.3 for the file dvdr985a_fus_eng.zip.
BTW, I've come here from the old DVD Plus forum.
