You can simply download the ISO and burn the update to CD-R here:
http://209.167.114.38/support/ceg/do.../HD-A2-1.6.iso
(this is a direct link from Toshiba Canada's support website)

If you dont have a burning program for ISOs, grab IMGBURN:

This is important info for the hd-a2 for firmware update 1.6
