Method to remove ads/trailers from BD rip?

[micro9mm]

I do backups of blu ray discs by re encoding to BD25 with BD Rebuilder, but my question is if there is a way to remove junk that just wastes space like trailers and the crap like "if you copy this you're a bad person" videos. I figure it would take a few gigs per disc off so if the quality is even just a little better, it's worth it. And be shorter to re encode too if there are fewer titles.

Thanks!

I actually find that MultiAVCHD works better than Clown_BD BD Copier to do this. The only problem is MultiAVCHD doesn't show you what titles are in the playlist and the preview function is sadly lacking. What I do is use Clown_BD BD Copier to view the playlist titles, then when I find the palylists I want to keep, I use MultiAVCHD to blank the rest. I found the remuxing option to be rather buggy so I just use it to blank the titles then use BD Rebuilder to resize the final content. There also seems to be a bit of a bug in MutiAVCHD when the movie is split to mutiple titles. I've had one movie so far where there were about 15 video files for the main movie and the last one was 00414.m2ts. MutiAVCHD for some reason decided the last file should be 00470.m2ts??.... I had to open the mpls with a hex enabled text editor and change the last entry to the correct file.
