Stealthray.swf with button that reads 'Next' anyone?

Hi Doug, welcome to Heroes!

Sorry for the delay in getting to this, but wanted to pass along the thoughts from our support team for anyone in the future who may have the same question:

I understand that you would like to customize the play button in the player bar. It is not possible to customize the player buttons in Presenter but you might want to look into using the Presenter player SDK to do so:

Since the SDK is not a supported product, we cannot offer advice on how to use the SDK or answer any functionality questions beyond what is noted in the sample documentation. Feel free to consult our dedicated Community forum where you can connect with other Presenter SDK users to share tips about developing content with the SDK:
