As a double-check, you should also print the value of $? immediately 
after rtmpdump is run (it should be 0) to verify that it returned 
successfully.  The rtmpdump command to get the help output (parsed for 
the version number) is executed slightly differently [via backticks] 
than the command to actually perform the download [via 
IPC::Open3::open3()].  You've demonstrated that the latter works, but it 
might be useful to know if the former is actually failing or just not 
returning output for some reason.

Just to double-check, if you run "perl -V" from the get_iplayer window 
prompt, what's in @INC (at the end of the output)?  For a get_iplayer 
install, it should look like this:

   @INC:
     C:/Program Files/get_iplayer/lib
     .

This isn't necessarily diagnostic since backticks is a builtin, but 
would at least verify for us that you're not picking up the other Perl. 
  And as a paranoid check if you're on Windows 7, make sure these 
directories do not exist:

C:\Users\<username>\AppData\Local\VirtualStore\Program Files\get_iplayer

or for 64-bit Windows:

C:\Users\<username>\AppData\Local\VirtualStore\Program Files 
(x86)\get_iplayer

The installer should have removed them, but worth a quick check.
