AJAX Tabs cache

hi,
I am using AJAX Tabs to display a number of videos. Currently the
video is reloaded every time I click on the tab, but I only want it to
load the first time so the video seek position is kept.
I tried setting "cache:true" and "'ajaxOptions':{ cache:true }" but
the video is still reloaded. Is there a way to stop an AJAX tab from
reloading its content?
