I am having exactly the same issue. I love UKMP & I used to use it all the time, whilst on the train travelling to work, out walking etc. I used to hit the shuffle button & have it on continous play - I could leave it for hours playing away song after song. I updated/downloaded the newest version of UKMP, which now includes the UKTUBE & the UKTUBE works brilliantly (although I have only downloaded one vido so far. But the UKMP will only play one song then stops, I cannot get it to play another without closing it down & then re-opening it. I am sure it must be something simple, but can anyone help me as I really love this programme. I have the latest version of python & mplayer I believe.
