Does an HDMI cable come with the standard installation or, do you get charged extra for that? Also I read where they allow you like two runs of cable at 125ft for the install. If I run my own cable, can I get say 1 cable of about 100ft as kind of replacement? I'm gonna run two lengths because I don't know if I will get SWM or not and, I want a HDDVR. Is there anything else I may have to cover the expenses for?
