I recently purchased a Sony MZ-S1 off of eBay and am having trouble with writing discs. I have tried MD Simple, OpenMG, and the plugin for Real Player. After I write the tracks to the minidsic, the player's display shows the rack name as if it is on there, but when I play it I get no sound. If I eject the disc and put it back in, the display tells me the disc is blank. I got these discs from a friend and suppose they might be bad, but before I go buy some new ones I just wanted to see if anyone had encountered a similar problem before. When he gave me the discs they had music on them and I could hear them fine.
