On the software side, you have to deal with your burning software, the format, you burn your DVD with (DVD+, DVD- or RAM), possibly mkisofs-Options and last not least the authoring software (in our case dvdauthor).
As dvdauthor is free software the author does not have the money to buy the official DVD-Specification but has to rely on what the unofficial specs offer and what can be found out by try and error approaches. This is why a dvdauthor-DVD is most likely not 100% conforming to the DVD-Specs, the hardware manufacturers build their devices with and thus not every hardware player will accept a DVD authored by dvdauthor.
dvdwizard tries best to produce conforming DVDs. There are not "features" - such as jumppad - that are known to break conformity. If your hardware player refuses to play DVDs authored with dvdwizard, you're out of luck, sorry.
The good news: I found out that the cheaper the player the more likely it will play self-authored DVDs. ;-)
