If you dont get any support from your hosting then reinstall. At, last part of UNA installing you will get cron link. Copy that link and go to your cpanel find cornjob. And add the link. Set all for 0 (zero). Then your video should work.
Did you not read above my friend? His host has crontabs disabled. Reinstalling UNA does nothing. And I can provide the crontab entry, I have it memorized from installing so many instances.
