Hi I am not sure if this is the correct forumto post to so apologies in advance. I currently own a Sony Walkman MZ-N710. I only use this sometimes when clubs I perform in use mini discs and do not want me to bring my own kit( I use a hard drive with usb and mixer.)Until recently all was well but the last couple of times when i have got to a venue the minidisc has not played in their players but could be played when my player was hooked up with the disc inside. I think that it is something to do with the transfer mode and the clubs players not supporting. I am at a loss at how to change this to how it was originally when I had no problem. Should I be using Standard transfer mode, Stereo transfer mode or what ? Please help. Also I recorded a disc in LP4 mode and now ehn I try to change back to a normail mode, the disc sqeaks. I seem to have doubled up the speed on the discs. Any help gratefully recieved Thanks Cooky
