Aw damn, I really liked having them all in one file. Any chance of also uploading a high bitrate combined file for each film (guessing it’d be in the 80GB range for each)?
And the problem is, for TTT and ROTK, the audio continues over the black screen that says INSERT DISC 2, so if you just join them at the cut to black without overlapping the audio from disc 1, you get a hard audio cut that’s jarring. This isn’t the case for FOTR, a simple join works fine for that one.
If he releases it as a BDMV, you can use MakeMKV to turn it into one file.
