The DVD standard imposes a number of restrictions on what can be included in the publication. Remember that DVD is intended as a playback format and cannot achieve the levels of interactivity possible in a normal Opus publication.
Menu hotspots must not overlap.
There is a maximum of 20 menu items on a single page.
There is a maximum of 70 menu pages per publication.
Hotspots must be static. It is possible to produce an animated hotspot in Opus DVD but when published to DVD the hotspot area will stay at the original location for the object so this should be avoided.
Quicktime (.mov) files cannot be converted.
The Browsers, DocView and QuickTime VR objects are not available.
Multiple windows or any functions that invoke extra windows (such as bookmarks or the publication search) are not available.
If any of these errors are encountered during the initial publish process an error will be reported.
