Title: Bs dsc 393 duration issues

it fixes outstanding issues in DSC-393:

- display a message if Carrier is CD-R or CD-ROM, duration type is "Default" and carrier capacity is not * min
- if speed is 0 or not selected, duration is set to 0
- Duration field is not calculated until both the Carrier and Carrier Capacity fields have been selected
