I've just recently started to see this media being advertised. From first impressions these look very expensive, around $10 a disc on most sites. I can't understand the high cost of these discs from a production point of view, surely it can't cost that much more to produce these? The only explanation, i can think of for the high price is initial pressure by the studios to keep prices high in an effort to put pirates off using these. For my purposes, i want to use these as backup and for home videos, but at the moment even if I had a capable DVD writer, I don't feel I could justify the extra cost per disc. DVD-R has always had higher compatibility, so i'm wondering wether to wait until the planned dual layer DVD-R discs appear. Does anyone think there will be any problems with compatibility with double layer DVD+R?
