what kind of dvd media are you using? low quality media will skip, become unreadable and deteriorate faster than higher quality dvd media…high quality dvd media is generally from japan and singapore.
what speed are you burning the dvd’s at? burning faster than specified for the media can cause playback issues such as skips, artifacting and it not working
lastly, have you tried multiple dvd player? it is possible that the media is of lower quality and a dvd player cannot read it like it can with high quality media or that its just a compatibility issue
