Date: 02. July 2005 - non of the provided links are working any longer, since BTC has removed all pages and support for the DVD-Burners on their page.
It looks to me, like they intend to "wipe out" all indicators for ever having produced and sold DVD-Burners - that is the crown of customer-support

People, be sure to keep the name and brand "BTC" in mind and for what that "Brand" stands for - since they are producing also other stuff...
