This has come up a couple times in the past and we've made some improvements to make it easier, so here's a tutorial about bookmarking a video. Normally, the Bookmarking template stores the page number as the bookmark, and all the variables in the suspend_data field in the LMS. This happens when the page changes.

If you want to store (and restore) the state of a single page, you need to:

1. capture the relevant information in a variable (or variables) and trigger the suspend call yourself,
2. and tell the page what to do when someone returns to it.

This general approach can be used for any type of interaction. A video's state is pretty much just the timestamp, so it's one of the simplest examples.
