Well, I've been having a lovely time tonight making what seem to be some very shiny coasters.
I have a DVD/CD burner which I know can burn proper DVDs because I've burnt two in the past three days. However, tonight I decided I wanted to burn a CD, so I booted up WMP and chose what songs I wanted and clicked burn. It -seemed- to burn without problem, but when I reinserted the CD and tried to play it (to see if it burned properly) my computer wouldn't recognize it as an audio CD. If I right-clicked on the drive and chose "AutoPlay", it would give me the options it normally gives for a blank CD, however if it wouldn't allow me to burn onto that same disk (it prompted me to insert a blank CD).
I thought maybe my PC was just being stupid so I stuck it in my Xbox 360 but it couldn't read it either.
So I thought hey, maybe WMP is just a poor CD burner (though I've used it to burn CDs many times) so I tried another CD burning program, to no avail. With this new program, however, if I inserted one of my "coasters" it would show in the program that there was, in fact, data burned onto the CD. I could also see this by holding the disk under a light and observing the blue ring that's there when you burn a CD.
Then as my big final resort I tried WMP again, closed every program I could possibly close, and burned it on the slowest speed possible (1x). This STILL did not work.
So now I'm stuck. I don't know what else to do! Has my CD-burning laser gone bad or do I just have some bad blank CDs (though they're Sony brand

)?
