If I use the preview function, VLC displayed a garbled screen wallpaper and the videos are scrambled. You can only see the cursor.
If I copy the dvd info “Nexus_Videos” (with the dvd files), into mswin. Rebooting to windows, VLC in mswin displays fine. I return to opensuse linux. I use dvd styler to create an iso file. Then use K3B to burn it to dvd-rw. If I put that dvd into a dvd player, it works fine.
Are you using ‘hardware acceleration’?
Try to turn it of. (I have swedish as language so this is freely translated) “tools -> properties” go to “input/codecs” and turn off hardware accelerations
the dvd standard is limited to 480 for region 1, and 576 for the rest of the world
as you are using everything from 360p up to 1080p don’t expect good results
if you are going to merge them the video’s need to be the same resolution
you’re better off asking/searching at their forum (it’s hosted on sf.net) https://sourceforge.net/p/dvdstyler/discussion/318795/
