Quick URL doesn't work ....

[Alan Milewczyk]

Just following this up, I'm really struggling..... I read some of the 
docs on substitution parameters and taking the first Autumnwatch 
programme which has a PID of b04n8zdp, I tried amending the example 
showing how to download "Top Gear"  with this for Autumnwatch|:

get_iplayer --pid ||b04n8zdp --tvmode=best --type=tv 
--file-prefix="<nameshort><-senum><-episodeshort>"|

I got the following result:
"get_iplayer v2.86, Copyright (C) 2008-2010 Phil Lewis

What am I doing wrong?

Thanks
