Can't you use the --fatfilename or --hfsfilename Output Option switches
on GIP's command line? I assume it works the same under Linux as Windows.

--fatfilename      Remove FAT forbidden characters in file and
                 directory names.  Always applied on Windows.
                  Overrides --punctuation.

--hfsfilename      Remove colons in file and directory names. Prevents
                  OS X Finder displaying colon as forward slash.
                  Always applied on OS X. Overrides --punctuation.

I had not come across --fatfilename. Thanks for drawing it to my attention. It says it is always applied on Windows. That explains why I have never had an invalid file name generated by get_iplayer even if the BBC puts in a colon (which it does not do as often as the other UK broadcasters). It probably makes sense for it to be the general default, or better to use a lowest common denominator character set across all operating systems.

As for the problem which started this thread, very slow HLSHD downloads in Windows 10 to an external 2TByte USB3 drive over a USB2 connection, I have now eliminated a faulty drive as the cause. The replacement is slightly faster at 2.5Mbit/s instead of 2.2Mbit/s but it is still 1/30 of the speed of downloading to an internal drive. The slow down does not affect a laptop with an AMD chipset and Windows 10 Pro. It does not affect a 1TByte drive from the same family. It does affect two machines with Intel chipsets running Windows 10 Home. One is a Dell Vostro 400 and the other is a Toshiba Satellite A100. There is a difference between them. On the Vostro the large file writing speed to the external drive without write caching is 10MByte/s. On the Satellite it is 25MByte/s, which is much closer to the 30MByte/s large file writing speed to the 1TByte drive. I guess it must be the USB driver, but they all claim to use the same 10.0.10586.0 driver version dating from 21/06/2006.
