I have to burn several copies of a DVD but not enough to make it worth sending away for duplication. i use Sony DVD Architect to author my DVDs but have been aware that simply using that to burn repeats is not necessarily the best way to go about it.
So I created an ISO from my first DVD using Ashampoo Burning Studio 14.
I then burned that image to a DVD (Taiyo Yuden Watershield 16x) using Nero 12 and it took 2-3 minutes
I then burned the same image to another identical DVD using Ashampoo 14 and it took more than 8 minutes!
Burning the already prepared project (so it's not an ISO, just the VIDEO_TS and AUDIO_TS structures complete) in DVDA comes in somewhere between the two.
A surprising difference, I think. Anyone had similar experiences?
