Hi guys, help needed! So I wanted to make Blu-ray ISO from two mkv files. I tried tsMuxeR, naturally, but somehow what I got was a message "some tracks not recognized and was ignored" and a video without sound on the output. I tried MKVToolNix in order to merge those two files in one and drop it onto tsMuxer again, trying to solve the problem, but the result was the same - no sound and an error message. The merged file was also kind of weird, as I tried to play it in VLC player, it stopped right at the spot where those two files were merged. ToolNix did show the audio was FLAC. So I take it neither tsMuxer nor MLVToolNix don't really work with FLAC correctly? Or what am I missing? I'm not too technically advanced, so I'd appreciate any input very much!
