You can temporarily fix this by changing rows 465-466 from:
[$lid, $title] = $GLOBALS['xoopsDB']->fetchrow($result);
$item_tag = $result['item_tag'];
to the single line:
[$lid, $title, $item_tag, $vidid] = $GLOBALS['xoopsDB']->fetchrow($result);
which should work (although I didn't try it).... I'll add this as an issues for the Beta 2 code on GitHub since it looks like it's still an issues there too.
