I noticed you are having an issue finding a partial language of content, you could extract the audio track from the DVD and add it to the copy you find on the seas.
makeMkv first and handbrake to compress. When using handbrake make sure to pick video and audio formats that work for your clients. I recommend h265 and eAC3 audio.
I only rip rare movies from dvds. It’s not worth the time and effort to rip dvds with it is easy to get 1080p copies of the same movies. An example of a DVD I riped is Enchanted Adventure.
Great work. Just watched today, they could have done better with the music, but overall great episode. Makes me wish they were 45 minutes to get a little bit more content in, feels rushed at times.
