For around twelve years we’ve been transferring video to DVD. During all of that time we have used DVD-R discs which hold up to two hours of good quality video footage.
It is possible to fit much more footage on a DVD-R disc. A few minutes over two hours is usually OK but once you try to get nearer to three hours the quality drop is very noticeable.
Dual-layer DVDs are available which hold just under four hours of good quality video footage. We tested dual-layer DVDs when they first came out. Compatibility with DVD players wasn’t great and at the time we decided not to use them.
Recently we revisited dual-layer discs and carried out some more testing. This time around the results were much better. The discs worked well in all of our equipment including DVD players & computers.
From now on we will be offering DVD+R DL as an option. At this stage we cannot guarantee that the discs will play perfectly but we do feel confident that a reasonably modern DVD player (last 5 years) should handle the discs just fine.
