Single layer, for a few reasons; my burner can't successfully burn dual layers, DL discs are still too bloody expensive, the source quality is so clean that I don't think I'd notice any benefit from the higher bitrate. Watching it now on my Sony 28" widescreen through RGB scart connection it looks stunning, makes the official DVD look like it was sourced from an old laserdisc or VHS, just a shame they used temporal smoothing to reduce the grain on the HDTV broadcast.

I think I'll have to boost the audio of the voiceover sections because few of the voiceovers are almost drowned by the audio from the front speakers, I'm sending a copy to another BR fan who has a higher spec setup than me to see what they think.
