The HD DVD high-definition movie format may have the lead in the U.S. porn industry, but Japanese adult film makers have turned decisively to Blu-ray Disc, breathing new life into its bid to replace DVDs as the disc of choice for home movies.

Sony Corp. said it will not work with the adult film industry to help put their movies on its Blu-ray Disc format, although it will not try to stop them completely.

Despite promises from Microsoft Corp. executives that the retail price of the new Xbox 360 game console would cover production costs, product tear downs by two different market researchers suggest that the company is losing money on the machines.
