Hi~ I got a big problem when using my new MD player RH1. I used to use SONY MP3 Player A608, I ripped heaps my CD into Atrac3plus 192 and 256k. All these files work no problem with my A608. But when I tried to transfer them into my RH1, I found most of them can't be transferred into my RH1, the sonic stage CP 4.0 promotes the error messages as " the file can not be transferred", "the transfer is prohibited". I never add copy protection when I ripped my CD, and I check the properties with these files, I see the "Remaining transfer count" are all "Unlimited". But I can transfer all my mp3 files with no problems. Something I found more wired is, some tracks I transferred to my RH1 successfully can't be transferred again 10min later, in some album, only the 1st few tracks can be transferred, the rest of them can't. I tried to reintall my Sonicstage CP 4.0, still doesn't work, then I try to transfer these file in my laptop, but still doesn't work. I went back to the shop that I purchased my RH1, they said they never see such kind of problem before, I wonder is this happen because I got a fault product? You guys are the only one I can turn into now. Desperate to have your help on this! Thanks!
