It's illegal, period.First off, I understand that receiver sharing or account stacking is not illegal - but rather is frowned upon by the satellite companies.
Imagine if you had 5 receivers and you gave four of them to your friends to use on your account. The situation speaks for itself. It's lost revenue for Shaw and they have good reason to consider it as being illegal.
You need to set up your own account with Shaw. You might be able to take the receiver with you and have it transferred from your parents' account to your new account, assuming your parents' account is in good standing.
If the receiver is programmed to use the satellite dish with the quad LNB that is the current technology, then you will need to have the same dish at your new location, but you can use either the 60e or the 75e dish with it's appropriate quad LNB. If you use an older style dish at your new location, you will need to let Shaw know and they will make changes on their end that will be sent to your receiver to enable you to use the receiver with the older dish. The older style dishes have LNB's that look like 2 cans. The newer quad LNB is a single unit that has 2 overlapping eyes and 4 connectors for the coax cable.
