@Trashcooky: Great guide, but having played with HandBrake on numerous occasions over many years, the output it generates on default settings doesn't even come close to what H264 as a standard is capable of, and it's simply not tweakable enough to get there with custom settings either as it doesn't allow the control or usage of some of x264's advanced and very useful features.
It's clear that the HandBrake developers have totally ignored all of the fine advice and recommendations given by the main x264 developer, Dark Shikari, on his blog page over the years when it comes to settings, which is a great shame. They haven't even gone to the bother of implementing an "Auto" mode for deinterlacing in their front-end, so almost all DVDs converted with it will
produce seriously suboptimal output unless the end-user manually enables it. HandBrake really is an utter shambles for non-techy users, and far too limiting for anyone who understands what needs to be done only to discover that some fairly important X264 options simply aren't available.
Have a crack at decrypting the DVDs as per your guide then feeding the resultant files into MediaCoder with my custom profile as linked to earlier and then compare the results. The difference really is enormous to those of us with fussy eyes, and the resultant files at just 10MB per minute of source material (so around 1GB for a typical 100 minute movie) are plenty good enough for even a fairly fussy viewer to watch on a full-size TV too.
