Recording issues with Philips DVDR 3505/37 (Philips DVDR3505 DVD Player/Recorder)

So far, my refurbished Philips DVDR 3505/37 seems to be working OK except for one thing. At times, when I record a movie, it will record and playback fine on the Philips DVDR 3505/37 but won’t play back at all on my Philips DVDP 3040 nor will it show up as anything but a blank DVD on my PC. I make sure that my Philips DVDR 3505/37 is set so that it automatically finalizes at the end of each recording and that it records so that it is compatible for other players.
Since this doesn’t happen all the time, I am not sure what is happening. Any ideas?

I have the same problem. My DVDs go through the finalization process, but I can not play them on any other device except my Phillips DVDR3505.
