[Plugin: W3 Total Cache] Gzip not working

Ok, so I enabled gzip compression on both pages and for minifying, yet I dont seem to get it to work. According to http://www.port80software.com/tools/compresscheckreport.asp?url=http://www.teleupdate.com&dolog=undefined and YSlow, about 10 files are not being compressed when they could. I have a forum in a sub folder with gzip compression enabled and it works properly, so I think I can say the problem exists at the blog level, either in the plugin or the .htaccess. I am not sure though what the mod does to enable gzip after it is selected. I also cleared all cache settings after, yet no luck.
