i had been thinking of switching over to ubuntu for the last many years but could not do so because i was not one of those people who thought it was a bit difficult one to grasp. I have finally installed it along with windows 7 on my computer. My computer is Dell XPS L502X which is a core i-7 with 8GB ram and 64 bit. i have installed 64-bit Ubuntu 13.04. so far i am not having a very good time because I can not watch any videos on it. the codecs are not there. and i tried to install vlc player but could not do it either. can someone please tell me how to install vlc or similar good player in 13.04 so that i can play my videos. also would it be possible to downgrade my ubuntu to an earlier version? would that solve the problem? or will someone sort out the bugs and stuff in Ubuntu 13.04 because I have tried to install several softwares using the codes avaialble on different websites but have not been able to do so.
