#17 DVD capacity selection (single/dual layer)

[Darren Salt]

Support for dual-layer DVDs (i.e. being able to choose whether the target is single-layer or dual-layer) would be useful, particularly since I've just acquired some reasonably cheap DVD+R DLs...

Incidentally, capacities as reported by dvd+rw-mediainfo:

DVD+R/RW = 2295104 × 2K (4700372992 bytes)
DVD+R DL = 4173824 × 2K (8547991552 bytes)
