Hey, didn't u ever use digit CDs? They all have HTML based interface and they autorun. Digit uses a program begin.exe to launch internet explorer, which opens the Agreement page. When U click on I AGREE button, it just opens a fullscreen window having the interface page.
I don't know whether u can use begin.exe for free or not, but u can try it in ur CD, copy autorun.inf and begin.exe to root of ur cd and change the paths of main html page in autorun.inf, and it will autorun.
Digit Guys, I don't know if using ur begin.exe is legal or not. If it is not, I would suggest krishnansurya to not to use the file.
