Did you try to burn them before getting WMP10? Has it ever worked?
WMP10 comes with a lot of new security features. Not for your security, but to pervent you from tempering with copyrighted music files. The web interface downloads malware and viruses just fine. It may have something to do with this, but I'm not sure.
I've had a sony S2 minidisc player for about a year or so and it has worked perfectly. I've filled about 20 minidiscs worth of music. I went out and bought a cd the other day, and then I tried to burn it onto a minidisc...only to get an error message saying that the file type is not recognizeable or something like that. I thought it was just the cd so I tried burning some downloaded music and that didn't work either. I have now come to realize that absolutely no files on my computer or from a cd will burn onto my minidisc. I always get the message that "sonicstage(program used to burn onto minidisc) does not recognize this file type"
The only thing that I could come up with to have cause this is me downloading Windows Media Player 10 a couple of weeks ago. Before I did that everything worked fine, but that's just my guess.
Please if anyone has any idea what the problem is or how to fix it tell me. thanks......
