VLC media player for Windows Troubleshooting • DVD to MP4 conversion – sometimes video speed spontaneously increases 1.33x and sound goes away.



Trying to use VLC > Media > Convert/Save to back up a few dvds.
Complete newbie here, but I’ve looked around and haven’t seen anything like this my problem as well as:
* tried 6 movies total
– 2 are fine
– 2 are fine for >1hr then vid speeds up by 1.33x and audio goes dead
– 1 has audio all the way, but vid is 1.33x fast from start
– 1 is ~1.04x fast vid for ~7 min, then vid speeds up to 1.33x fast, then at 19:40 the horribly unsync’d audio cuts out.
Tried
* 2 different computers (1 is Windows 10, one is Windows 11) -> super similar results on one of the dvd that stays fine for 1+ hour, then goes screwy
Tried some advice from https://forum.videolan.org/viewtopic.php?f=2&t=156428
#1 couldn’t find especially nVidia on my Windows 10 computer, but given 2 computers, this wouldn’t seem like a good candidate
#2 tried vlc versions 3.0.18 & 3.0.20 -> super similar results
#8 – Try Preferences -> Input/Codec -> HW accelerated decoding to “None”
-> I set Hardware-accelerated decoding to “Disable” -> much bigger file but same results
#9 – On Windows, try Preferences -> Video -> Output to something different (dx11 or d3d)
-> I set Hardware-accelerated decoding to “Direct3D11 Video Output” AND Hardware-accelerated decoding to “Direct3D11 Video Acceleration” -> same results

This (VLC conversion) seemed like such a great idea. VLC plays the disks just fine so the input-to-screen-output seems to work, “all ya need to do” is take the screen-output and turn it into MP4 output file. How did this go so terribly wrong … and only sometimes?

Thanks in advance
