If you play some trailer and in the middle of trailer go to next or previous and start playing that pag etrailer. Then you can hear both trailers but u can watch the present one. By default if you to next page or previous the earlier page vedio is not stopped.
I more or less agree with your views, however I dont think Delhi 6 deserves to be in the list. I reckon the trailer of Paa deserved more. And yes, 99 had one of the best made trailers which actually enticed people like me to watch the movie... specially with the line saying.."the difference between 99 and 100 is just 1 but that 1 is a big 1." superb. Also I must applaud you for keeping DEV D & GULAAL highly placed. Indeed they were the most shocking and daring trailers of 2009. Finally Anurag is going places. Good job Raja.. I have always been an admirer of your work. Way to go!!
