i use this all the time
only use the simpler features and have no probs with it
1) load or drag & drop your movie/audio files into dvd lab pro
2) load each movie into the movie resource area
3) click the wizard icon to create chapters
4) create your menu background
5) create a link item, text or button
6) set your project & temporary directories
7) hit the compile button and done!
this is just the basics.
you can try this out then expand your knowledge later.
(mods : i'm using allyoucanupload.webshots.com to host these pics. let me know if this is okay ... gulp!)
hope this helps mate.
