The hate for DL? It's just not as reliable, even Verbatim DL aren't great, I simply don't trust them at all. I lost hundreds of Gigs of photos, music movies etc. because i backed up on unreliable media, and i'm still kicking myself for it now.
Not to mention the massive cost, slow burn rate, difficulty to obtain the discs, compatability issues and the whole load of baggage to go with them.
Since i started using good discs i haven't had a single coaster. I've burnt well over 100+ with three drives using TY and verbatim discs and the only coasters i've ever had were due to poor media (before i realised just how bad the budget brands were)
But by all means, for some people DL is worth the effort, but i doubt the OP is if he didn't know what to look for in the specs.
