I took a much closer look.
I tried to do an Audio CD with only 2 tracks from 2 mp3 files.
It start the conversion. I see that "Adding Track 1 of 2" and
the green bar goes to 1/2.
I Open the folder:
C:\Documents and Settings\Joshua3\Local Settings\Temp
where I can see the file: tmpE0.tmp = 0Kbytes
and the file: tmpE0.tmp.wav growing from 0 bytes to 20 GigaBytes moment
when I stop CDBurnerXP running just because it seems clear to me that
it will eat, again, all the free space from C: partition (60 Gbytes free there).
I run the same test 3 times. Every time same thing is happening: C partition is running out of space
and CD BurnerXP is a "not responding" task.
I did the same test using InfraRecorder (free version) and it was
able to create the audio CD using the same mp3 files in about 5 minutes.
