So here is the problem, I have been ripping my DVD collection for use on my
TV. After i get the video file from handbrake i put it through lostify or metax to tag all the metadata. Everything has been going smoothly except for the handful of movies i have that are spread across two discs (LOTR, Sleepers, etc.). The only program i am aware of that will stitch two files together is quicktime pro. However, the resulting file is a mov and all chapter data is lost in the process. Plus, lostify doesnt work with mov files.
Is there a program out there that will combine two m4v files without changing the file extension or losing chapter data? Has anybody else had this same problem? Any solutions or workarounds out there? Please help.
