input source selector is not at the correct position.

A finalized disc has been inserted. Use an unfinalized recordable disc.
An attempt has been made to create more than 32 program steps.
There is no space on the disc, or no tracks are available, or a general recording error has occurred.
You are trying to do digital direct recording from a source which has not been recorded at 44.1 kHz
("Digital direct" on page 23).
The disc is bad. If it is a CD-RW disc, you may refresh it ("Refreshing a disc" on page 26), otherwise
replace the disc.
