I should clarify.. It doesn't matter if the intro is at 720. The menu issue I had, was due to using the same clip just to have something there to satisfy the requirement of a motion menu...
At this point, it's probably best if I start from scratch with a chosen clip in background. Each menu can have different clips, as well.
The only other issue was that I couldn't add scene markers with this software, but if it's possible to use tsmuxer *after the project to insert them and have it work, it may still be possible to be able to skip via "next" button on playback. Something about the frame rate it didn't like, which is odd.
Edit: Also, used a font called "Star Jedi" for the menu text. Open to suggestions, as well as input on layout preference. 21 audio selections fills up a screen. Not sure if I prefer that, or two screens, but it can all fit in one. Subtitles, I will probably just do one popup menu for.
