What program will create flash thumbnails on a DVD chapter selection screen?

[badluck]

I was at a conference last week and a guy created a DVD that had multiple movies on one disc. He used a regular set top DVD player to play it (one that could be bought at Sears, BestBuy, etc.). When he loaded the DVD, the selection menu had 4 thumbnails to choose from. The cool part was that each thumbnail had a 5 second looping video (with no sound). Seemed pretty cool and I would like to re-create this effect.

Does anybody know what software I can use to create something like this? I'm not sure if they were flash thumbnails, but that was my 1st thought when I saw it.....
