Can someone help me watch older programmes on Demand Five on a Mac? It seems from what I'm reading that they switched to Mac compatible videos in January 2009, but older videos come up with the message: "Unfortunately you can't watch this programme on a Macintosh because Windows Media Player doesn't support the security features used to protect content".

Is there any way round this? I've a feeling the answer is going to be 'no' but want to make sure.

I'm using Firefox if that makes a difference.
