To do this, you will need Firefox with Autoscroll for musicians add-on and you will need Flash (or someone that can create a swf file for you).
Install the add-on and export the seating chart to an HTML and place it on your desktop. On the bottom right corner of firefox, there is a music note. Click on it and set it to active, slide the slider all the way to the right to get a decent scroll speed. Open the seating chart in firefox and time how long it takes for the entire list to scroll through.
Create a Flash document, set the frames per second to 1. If your screen takes 35 seconds to scroll through all names or tables, insert a keyframe at frame 40 (5 seconds for players at bottom of list time to see their seat). Go to the actions panel and use the get URL command and enter the address of the HTML file you exported (on desktop). Save and publish this to your desktop (you only need the .swf file).
Next, edit the Tables export template C:\Program Files\The Tournament Director 2\templates and open up the tables export template with a html editor. Insert the swf file and set it's size to 1px X 1px. so it doesn't show up when on the screens.
Plenty of work, but I've already tied it out and it works..
Autoscroll link
https://addons.mozilla.org/en-US/firefox/addon/6515After every seating change, go to the tables tab and export and overwrite the HTML file on your desktop.
The autoscroll will slowly scroll from top to bottom, and the swf file embedded will reload the pagfrom the top.
Hope I didnt leave anything out...
