We have a client that wants us to author a very long video (3.3 hours, but it's essentially 10 seperate videos) onto a DVD.. We're thinking dual-layer is probably the best way to achieve this and I can't really find any information regarding dual layer compatibility with most DVD players.. Most of these will be likely played back on PCs/Laptops.
Would it be safer to do just a 2 disc DVD, or is dual layer disc playback not really a compatibility issue anymore?
I'm assuming that you are not going to be replicating (ie. creating a glass master and pressing) the discs.
If you are going to be just burning the discs, the compatibility level for dual-layer discs are still not that great.
If you want to play it safe, go for the 2 disc set.
