after encoding the extras I found there was another 400mb spare so I re-encoded the film's video to a higher bitrate, 7900kbps avg, 8800 max.I just ordered 10 DL discs and 50 SL discs, I chose printable even though I don't have a printer that'll do them so those who do can print the label themselves, plus I hate the brands logo splashed all over the face. The DL prices are almost reasonable when you get successful burns, but if they fail you end up with £2.40 DL coasters compared to 24p SL coasters.
