Switched menu

Hi,

I'm using Q DVD-Author to create a menu template, then modifying the xml file to create a "switched" menu like the one described at http://www.geocities.com/samanthalane/dvd/index.html .  I have 5 videos and 5 different menus (each with only one button), Q DVD-Author appears to have created 2 titlesets out of those.  I've created ActionDown buttons for each menu which work great to cycle through each of the menus.  "Select/Enter" plays the titles from each menu properly - until it cycles around to the top menu again.  When it does that, the button is already highlighted (selected), and pressing "Select/Enter" doesn't play the video assigned to it like it does when the DVD is first played.  Pressing "Select/Enter" in the first menu, after cycling all the way through, sends you to the next menu like the ActionDown button does.

I hope this makes sense, and I'm hoping someone can spot an obvious error or omission in the following relevant XML files:
