Some time ago my son-in-law replaced my windows operating system with Ubuntu.
I was very reluctant but now absolutely love it but for one thing. It has, within the last couple of months, stopped playing videos. ( The main use for it is the BBC News web site and their vids will not play at all.)
I think it was caused by one of the regular service downloads but I haven't a clue how to fix it. (Son-in-law lives a great distance away and is very busy plus I'd like to stick it up him by fixing something myself for once and not always having to bleat on at him till he comes up and fixes it. )
I think I may have to delete something on my pc and then re-install something else?
Can anyone put me straight and in a very simple way. I'm a silver surfer and not much good with computer speak.
