[QUOTE=lawrywild;2032048]These were burnt in a GSA-E10N, at 2.4x, with ImgBurn. Not sure of exact date but must’ve been around 4 months ago. I didn’t have a drive to scan then, but verification and TRT were perfect, now on the same drive, it’s barely readable… (I did however manage to get the data off intact (LG ftmfw!))
I didn’t save pics of the scans of the other discs, but they are all pretty similar to this one… They were all stored in a Amaray HD-DVD Box (high quality), most have never been touched since burn. The burnable surface below the disc can only be described as ‘wavey’. Lots of wavey lines are visible… 
PS: One other disc had 500000 PO Failures :O[/QUOTE]
Dunno if that’s degrading, just looks like a shit burn that has typical errors at the layer break and right at the end of the second layer also.
2.4x was probably too slow of a burn speed. I think DL should be burned @ 4x minimum these days. Would you burn a SL disc @ 2.4x with good results? Probably not so I tend to apply the same reasoning with DL discs.
Initial scans would have made this a clear cut case but we don’t know the original burn quality.
Monitor the disc from now, post another scan to this thread in a months time. If it is indeed degrading fast, there will be more degradation in one months time.
