The same issue exists with video on FB. I naively submitted a Maemo browser bug report for this & was told to ask FB to allow older versions of Flash. I did & you can see for yourself how well that turned out.

BTW, I've noticed that Hulu.com is now requiring the new flash player, too. (Not that the site was really usable before.) Unfortunately, it looks like the usefulness of the tablet is going to gradually wane over time due to this issue.
