2 single layer DVDs vs 1 dual layer DVD?

Hello!


here is my question





Is there a size difference between 2 single layer DVD+R, and 1 Dual Layer DVDR? I was burning recorded TV Shows, and they would not fit on a dual layer dvd (it was just about 350 megabytes more), but they did fit onto 2 single layer DVDs, with about 200 megabytes to spare.





I have always though that a dual layer dvd was comparable to 2 single layer dvd.





Can anyone explain the difference in disc capacity?





it might be worth mentioning that I used Nero 7 to do the burn. Not the Nero express

2 single layer DVDs vs 1 dual layer DVD?
single layer 4.7 GB dual is 8.5 GB so there is a 900 MB difference between two singles and a dual
Reply:There is no size difference -- they are both 12 cm. The capacity is different ...





DVD-5 (12 cm, SS/SL) = 4.70 BB


DVD-9 (12 cm, SS/DL) = 8.54 BB


DVD-14 (12 cm, DS/ML) = 13.24 BB





DVD-R 1.0 (12 cm, SS/SL) = 3.95 BB


DVD-R 2.0 (12 cm, SS/SL) = 4.70 BB


DVD-R 2.0 (12 cm, DS/SL) = 9.40 BB
