The speed of writing to DVDs is limited mainly by two factors, the speed capability of the writer and the speed rating of the media used. Both these factors have been steadily increasing but your speed is always limited by the lowest one. You might have the latest 16x writer but if the media is only 2x then that's the speed it will write at.
This I understood for the years I've been writing DVDs on the computer but I also write to DVDs from TV using Panasonic DVD recorders. Mostly it will be in real time but as my latest one also has a HD there is the option for High Speed dubbing. I just went to transfer some shows on the HD to a DVD-R using High Speed and it said it would finish in 7 minutes. I let it continue and yes, it did finish in 7 minutes. To make it playable on all DVD players it needs to be finalised and that takes less than one minute so it would take 8 minutes to burn 157 minutes, that's about 20x speed and the media is a cheap one rated at 4x. The disc seems perfectly OK so how can that happen?
