Hey guys this is my first MD and my first post so here goes.My parents just got back from china and they got me the Sony MZ-N920 which i love.The thing is it came with no manual(id asume it wouldnt be english anyway)so i cant work out a few things: 1.How do i wipe certain tracks from the disk 2.How do i wipe the whole disk 3.Can i extend the record time past 74 mins. I hope i havnt come off like a tool but i guess i am,look fpward to many more discussions in the future!!!!!!!! Cheers matees!!!!
