BTW US channels have such interesting thing like affiliate. So if for normal channe we haveI asked the basic question about Logo's on the MP1 atsince all this stuff is useless without such enthusiasts.
@Jasmeet_181 Gave me a link to his Google Code
Channel - Alias
but for US it's
Network - Local affiliate - (Alias)
So affiliate station could be alias itself or have subordinary aliases.
Some stuff to think about db model I don't say we should change but we need to place weird US channels into it somehow.
