Should I be able to read a dual layer disc that I have burned in my Pioneer DVR-108, in a Pioneer DVR-107D? It read's fine in my DVD Video Player (relatively new) and fine in the DVR-108 (where it was burned), but the DVR-107D does not recognise it at all.

The media is Verbatim 2.4x certified DVD+R Double Layer.

Apologies, I think I've found the reason:

"Other burners, that check disc ID codes, won't recognize a DVD+R DL disc because they don't have the DVD+R DL disc ID code in their firmware. Even when a disc has been recorded and finalized, other burners still look for a media code and generally will eject a disc without one. Sony has recognized this and will be making a firmware upgrade available in early May that allows Sony's 510/530 customers (500 most likely as well) to read/play a finalized DVD+R DL disc. Sony can't say how other manufacturers will handle this, however, we don't expect that many users will be playing back discs in other burners."

I thought the same thing, but the DVR-108 sets the book type to DVD-ROM by default with DL media. While I haven't tried it myself, the DVR-107 should (in theory) be able to read it then. Anyone know?
