Yes, sorry, you're right. Didn't try it and didn't see the warning.

Unfortunately the readfunction isn't mine it's the MP4Read function from
libmp4v2.dll so I'm not sure why it only works with IP addresses and not
host names. Your right I should really do some error checking because if
GetHostEntry fails to resolve the host name it throws an exception.

Thanks
