Okay I used bd rebuilder, and it works okay, but sometimes i notice flaws in the picture, like un colored segments, and it takes forever from my dual core. I used ts muxer and get perfect picture and good DTS audio, which i burn movie only to 25gb disks. Now I have dawned on downloaded mkv files which are 2 to 8 gb in size, and the picture is as good as the original, probably from x264 encode.
Lately i came across a great program multiavchd, which allows me burn 2 to 5 movies, from the downloaded mkv files to one 25gb bd-r, without no loss in video quality from original.
The only problem is some mkv files weren't compliant and i got no video from them. Any way to convert them to make them compliant or to shrink down my m2ts files from a actual real movie disc to mkv x264 so i can put multiple movies on one 25gb disk without loss in video, with dts audio?
Note, I only tested on ps3
