I have a new (to me) laptop. I have cleaned and wiped the windows, and I am up and running on Ubuntu 12.4.

Everything is working ok, with the exception of my ability to play videos. I have followed the instructions in the "sticky" and most of them are working OK. Some videos refuse to play however and either are blank (thumb doesn't even show), or just hang when I click on the play button.

My laptop is an HP-Pavillion DVD-7. 500-Gig Hard Drive, 4-gig memory, graphics processor is VESA:RS780, running on an AMD Turion X2, Mobile RM-72. I am running the 32-bit Ubuntu.

Can you tell from my specifications, if the problem is the hardware, or if I need to keep pounding away on the codecs and 'add-ons'???
