BBC: No iPlayer for the Mac
The BBC has launched VOD (video-on-demand) services and offers a lot of programs in this way. Unfortunately, those are only available from a PC, the Mac has been set aside.
Good or bad news depending on your OS. They have announced that they will offer compatibility Mac OS X at the end of the year.
They have not forgotten the Mac, but it seems they are in no rush to provide the iPlayer for it.
Update from neil at mac.com:
The BBC iPlayer for Mac has been available for weeks, but streaming
only using Flash.
The download version due later this year.
