The BBC says it has fixed its iPlayer online TV service to prevent users downloading programmes that were intended only for streaming on an iPhone or iPod Touch.
Hackers had breached the Digital Rights Management (DRM) system on iPlayer, enabling them to save the programmes to a hard disk and share them with others.
The BBC admitted it was most likely facing a cat and mouse game with hackers intent on circumnavigating the copy protection.
"It's an ongoing, constant process and one which we will continue to monitor," said the Corporation in a statement.
The BBC announced a version of iPlayer for the iPhone and iPod Touch last week, as we reported here.
