Dvd-r Dl

[Perplexer]

Hi.

If I understand correctly the DVD-R DL media comes with the BookType set to DVD-R and cannot be changed. Now if I have an old standalone DVD player which does not support DVD-R booktype and cannot be firmware upgraded, then my only option would be to buy DVD+R DL disc and burn it with BookType set to DVD-ROM ? If that is so, would it mean that DVD+R/W/DL media is (can be made) 100% compatible with all DVD players and DVD-R/W/DL is not ?

Thanks for the answer(s).

This booktype is so old that the only reason for this would be that the player is blacklisting this booktype

would it mean that DVD+R/W/DL media is (can be made) 100% compatible with all DVD players
No, but close to, assuming that you don't use crap media
and DVD-R/W/DL is not
The difference is only important for DL media. DVD+R DL (with booktype dvd-rom) is much more compatible than DVD-R DL. The problem is that a lot of players don't expect a disc with booktype dvd-r to have 2 layers.
