I have a Tivo where I cannot run a phone line, wireless modem doesn't work and don't have a network, wired or wireless. I can connect to an unknown, unsecured wireless network. Are there any risks to "borrowing" that wireless network for downloading guide data? Other than the obvious risk that the owner could wise up and lock down the network. If this has been discussed before, I'd appreciate a pointer to the thread - I tried searching, but came up blank.
