Dear Ignatz, Thank you for these questions. My responses in bold.
Here's some questions. Answer all you can.
1: What application are you using to burn?
Windows Media Player
2: What format are the source files? Mp3? WAV?
WAV
3: Have you tried to play back on several different devices, both PC and non-PC?
I don't have any other devices. I play all my CDs on Windows Media Player. Yes, the source disk plays fine. It's brand new.
4: If you look at the burned CD in Windows Explorer, can you find the burned files? Give us the name you see for a file or two.
The burned/blank CD doesn't show anything. A window pops up that asks me if I want to burn it.
5: Can you think of anything you did differently for the successful burns? Different burning application? Different playback devices? Different type of source files?
That's my problem -- I don't remember what I did. I thought I did it exactly the same way I'm trying now. Same everything: Same burning application; Same playback devices; Same type of source files.
6: What exact type of blank disks are you using? Brand? "Music" discs or "data" discs"?
Same ones I have been using, forever, to make new music CDs. They are Office Depot CD-R 52X-700 MB
7: Where do you want these burned CDs to play? In your car? From a PC DVD drive?
Don't know exactly. I'm taking the burned CD to my Yoga teacher, who has an inexpensive, portable CD player. The thumb drive goes to another class, and would be transferred to that teacher's system. I don't know what her system is, but she asked me to bring a thumb drive. I think a CD would work for her, too.
