My Philips dvdr75, now 5(?) years old has given fairly good service but has recently started to refuse to read dvd's that are part recorded and gives a 'empty disc' message. The home screen can also give 'blinking' film icons. It usually palys pre-recorded dvd's ok although sometimes I get unrecognised data messages! Is it a case of taking the recorder to a specialist for cleaning (is this cost effective?) or is it a case of laying it to rest? If it's the latter, what do I do about all my part recorded dvd's that have not been finalised? Any (sensible) advice appreciated.
