"The terrestrial TV company's popular 4oD service, which offers
viewers thousands of hours of archive TV shows and films to stream,
download or rent, remains a Windows XP and Vista-only domain, C4
told The Register.
"Mac and Linux users, as well as Firefox fans, will continue to
be frozen out of the service.
"The only web browser currently supported by 4oD, which runs in
Windows Media Player 10 or above, is Microsoft's Internet Explorer
versions 5.5, 6 and 7"
