2 quick fixes ( you dont have to follow them to have it working) - I made these changes to get a valid XHTML 1.0 Transitional.

1. In the plugin "Make changes to 'threadbit' template"

Look for this:

$vbulletin->templatecache['threadbit'] = preg_replace($find, $match[0] . $match[1] . ' ".(($thread[\'open\'] != 10) ? ("<img id=\"vbpostimg_$thread[' . $postidtype . ']\" src=\"$stylevar[imgdir_button]/expand.gif\" onclick=\"return vbpost_get($thread[' . $postidtype . '])\" onMouseOver=\"this.style.cursor=\'pointer\';\" title=\"' . construct_phrase($vbphrase['click_here_to_read_the_x'], $titlephrase) . '\" />") : (""))."', $vbulletin->templatecache['threadbit']);

replace with:

$vbulletin->templatecache['threadbit'] = preg_replace($find, $match[0] . $match[1] . ' ".(($thread[\'open\'] != 10) ? ("<img id=\"vbpostimg_$thread[' . $postidtype . ']\" src=\"$stylevar[imgdir_button]/expand.gif\" onclick=\"return vbpost_get($thread[' . $postidtype . '])\" alt=\"' . construct_phrase($vbphrase['click_here_to_read_the_x'], $titlephrase) . '\" />") : (""))."', $vbulletin->templatecache['threadbit']);

I took out the onMouseOver and changed TITLE to ALT.
