Just out of curiosity, does anybody know of any DVD players capable of playing unfinalised DVD-R/RW & DVD+R, or is this effectively restricted to recorders only?

Does the Pioneer DV-575A read unfinalised discs?

As its unfinished, only recorders can read the discs.

Thanks mjn, but recently I read a review of a Yamaha DVD player which referred to Pioneer players, and mentioned that the ability to read unfinalized DVD-Rs seemed peculiar to them. I haven't confirmed that they do, but if so I wondered if any other manufacturers make such players.

Unless the specifics of incremental writing (multi-session) of DVDs vary between manufacturer's implementations, there seems no reason that a regular player (maybe with commonly found DVD-ROM drive) couldn't read unfinalized discs in the same way as recorders, with suitable firmware.
