Issue with VLC ripping private DVDs with more than 2 hours of content (more or less - actual breakpoint unknown)
This may not reproduce, as I cannot say that the DVDs were authored in any canonical/approved way.
And I have worked around this with Handbrake, and am posting this just for the record.
So ..
About 25 years ago, I transferred - to 6 DVDs -Camcorder tapes of my kids to a PC (probably with a video capture card) and then to DVDs
After much confusion and blind alleys, I am reasonably certain of the following:
1) if the DVD had more than 2 hours (or so) of content, VLS created a 6+ hour mp4 file (6+ hours being the length of the VLC playback and consistent with the 4GB size of the file and the resolution of the content). The first 2 hours are repeated two additional times to get up to 6 hours/ 4GB.
2) one of the DVDs had 5 hours of content and the mp4 produced was a hot mess. As above,there was a 6hr mp4 file created, but just the first 2 hours repeated twice again - last three hours were nowhere. Audio cut out 1 hour into it. MP4 explorer showed two titles - a 2 hour one and the second one had a nonsensically large length. This mp4 caused a lot of other software to malfunction - PRISM, Handbrake, Media Player, Windows Media Player, Stock Android video player, PS4, MP4Tools,SONY Bravia smart TV, MakeMFV, ffmpeg and Iphone.
