I can't open Youtube.com on computer with lubuntu and mint. I see that my flash works properly on other sites. Problem is in for example on youtube (yming.com loading without endless) and vimeo. I tried to use firefox and chromium. I thought that it would be problem with dns (I have dns from DHCP - opendns) so I changed to google dns but it didn't help to solve problem. When I use text browser - Links these site are opening well in text mode. I think that the problem is with flash or java. On other computer with windows connected to the same network these sites are being opened without problem.

I am on the point that I don't know what to do next, because I tried to install and uninstall flash several times. I tried Flash-Aid as well.
