Working on burning CDs to free up disk space. Three basic problems:

1. Nero (6.x) didn't recognize the .flac file extension, but he found a plug-in to resolve that

2. One audio file that plays just fine (through winamp) from the downloaded file, but each time he's tried to burn it, the last half of the track comes up pure silence; and

3. Nero doesn't recognize the mp2 file format. Winamp plays them just fine; he just can't burn them to CD.
