Hardware is either Motorola VIP1262 Main set top with VIP1200 secondary set tops. Unless installer uses newer model which should only be used for someone wanting 500 GB hard drives (existing units are 160 GB, and if new units are used they are restricted to 160 unless you pay extra for the 500 GB service)
Many installers use the new one anyway. They load quicker and are all the same size.
The service has 3 streams. They are just rolling out an update from 2 HD/1 SD to 3 HD.
Not sure if/how much the Internet is affected by tv use. Maybe none since they eliminated Bolt and Super Max Internet plans.
