It takes apporx. 2 hours per title from beginning to end. I use a 5-year old Dell dual-core based computer, XP, 4Gb memory, 2Tb secondary installed HDD for the process. Software installed includes AnyDVDhd from SlySoft, ClownBD (full install including tsMuxeR, eac3to, BDSup2Sub, ImgBurn, Java runtime). Go to
www.mediasmartserver.net/wiki/index.php/Clown_BD for a tutorial on how to run ClownBD. I follow all the steps with the following exceptions: I deselect 'Use ImgBurn' on the main screen, on "eac3to 3rd Pass" screen I deselect ALL subtitles, select only 1 audio type and channels, select "Movie Output Format" as Blu-ray. At that point once you select next, it will take a long time to convrt (up to 1.5 hours). When complete, I navigate to the Clown_BD folder created and navigate to the BDMV/stream to see the size of the stream file.
The reason I deselect ALL subtitles, etc. is to get a perfect copy of the movie that will fit on the BD-R. In most cases, the extras, etc. are really not necessary. I have done this for 30+ movies so far, not counting the ones that are > 25 Gb. I'll watch for bargain deals on the others down the road.
