Caching problem in version 1.1?

Hi,

Firstly, i would like to thank Ivan  for the new version, which seems to be a nice job.

We installed the new version of the plugin, but we have a problem to watch the video more than once, and we don't yet know how to fix it.

We can first watch a new uploaded video. However, the next time we wanna access, the video is not streamed.

We think, it could be a cache problem, because when we change the selected player and we access again to the video, the new player won't appear.

We already disable all the cache settings on the site administration, however it didn't fix the problem.

Any hints or solution will be wellcome.

Many thanks in advance.
