EOFError: 4 bytes missing

BBC iPlayer support is very hit and miss. Some URLs work fine, others error out with this error message. The error is always "EOFError: 4 bytes missing" but it happens at different times on different attempts. I am unable to test whether this error still occurs without the SOCKS5 proxy as iPlayer only allows UK IP addresses to connect to its service.
