Our platform (BrightTALK) publishes recorded versions of webinars immediately after the live event concludes, so we typically just pick a time zone for the live event and send the on-demand link to everybody who missed it.

Hi Anna,
1. You can't sync multiple GTW's to a single Marketo Program.
2. I haven't tried this
3. You could use Marketo segments on the language field of a lead. You can use segments for dynamic content in your Marketo assets. Let your international teams provide you the translations for it. This enables you to use a single Marketo Program and GTW session for all languages. However the GTW session it self is only in one language of course.
