I modified tvBookmark.xml file by adding mms://mediastreamservers.gtk.hu/Super_FM and audo/mpeg format, but w/o success. i tried audio/wma, audio/wma2, audio/mpeg... It did not work.
p.s. for a long time i have tried to find youtube player with such directory structure as mentioned
but just for few days i changed my InfoLink country to CIS on ServiceMenu and i have got another youtube widget!. Now i can modify xml file and add my own stream urls. As you know, there are two types of youtube widgets. One for east europe (especialy for russia i think, called CIS) and other, for all other countries. I think this topick isn`t popular because all you, people, are using not right version (for modifying) of youtube widgets in case selection your country. Try it and work out solution for listening radio from internetFind /mtd_down/widgets/normal/200000103/ucc.js
