First of all I want to say that BTC support was released practically 
untested, as the user who provided the information about BTC extension 
never replied to the request to verify the suggested code.

Modify dvd+rw-booktype source code to print an explicit error code:

        else if (ASC(err)==0x3A)
            return fprintf (stderr,":-( BTC_FAh: no media mounted\n"),1;
        else
            sperror ("BTC_FAh",err);

Can you test it with some rewritable media? A.
