Amazon Instant Video on the A500?

I am currently running Thor Tegra-Owners ICS v156 on my A500. I am wondering if any of you have had any luck trying to watch Amazon Prime Account Instant Videos? Only the stock browser will even try to play one (Opera and Firefox don't even recognize the "play" button as click-able). I have Flash 11 freshly updated from the Store. The stock browser will start to load a movie I have selected and while the dots are supposed to be progressing left to right as it loads it finally freezes on the first dot and that's it. No video.

I've seen mention of using PlayON, but since that is a retail app and also requires it's PC side be running I would rather just use a browser on the A500 if possible. Any comments will be appreciated.

Well, after having some issues copying files by USB under the ICS ROM, I decided to go back to Thor's HC 3.2.1 v14.2, and once I did, I am now able to use the stock browser to watch Amazon Instant Videos.
