Hi Ralph

I suggested ignoring CR because they are there.  Ideally they would not 
be there.  The files are internal to get_iplayer so they can be in any 
format.  I would have thought it sensible to use LF as a line terminator 
for get_iplayer's internal files across all operating systems.  The 
question is how the CR are getting into the files in Windows.

Since the script uses
print \n
the answer must be that Perl is translating \n as CR LF in Windows.  If 
Perl can then handle the variants portably with chomp VARIABLE that's 
fine, but it doesn't seem to be working properly at the moment. 
Otherwise the solution may be to replace \n with \015.

Best wishes
