AudioCD is not usually a file size issue. Without detail I can't guess why this happened but WMP isn't a great tool for this. Try CDBURNERXP next time.
I have flac music files, and have used MediaCoder to convert these flac into mp3. When I then drag these new mp3's (converted from the flac) into Windows Media Player to burn a standard music cd, they bring on an error message saying File IS Too Large to Burn. even thou the mp3 file is only 7 MB for example.
Windows Media Player will still accept and burn other mp3's- just not the ones that ive created from flac.
Anyone know how to solve this?
