I got one too and at first it scared the #*$! out of me because I thought they were going to close my account :)
I have changed my site (easy since I use an include file) but like everybody else, if I don't gain anything from it I'll switch back in a heart beat.
The 300x250 gives you fewer ads than 336x so if the video ads are not good and not targeted it probably will mean less income.....
