By using 2 - 5% more of a BD disc, you will not see a difference in video quality. And you risk errors on the outer edge of the disc. Plus they take longer to burn. There's no factor which would make me elect to use the full 23.2Gb of Disc space. That's asking for trouble. I prefer go with 22.0 - 22.5Gb. However if I remove audio tracks, and no encoding is required, and I end up around 22.7 - 23.0Gb, that is acceptable. My LG drive seems to have trouble closing LTH discs around the outer edge. Jdobbs hit the estimation algorithm right on the money!
