My first post here, I am renting an apartment in a private home with Rogers Cable service included in rent, I was given a Rogers box Cisco DTA 50 there are two apartments, my neighbor was given the big box with clock display, he gets different channels than me including Sportsnet which shows the Toronto Bluejays which is what I want, I get TSN
Also, IIRC, that DTA 50 is capable of only standard definition, which means most shows will be letter boxed in a 4:3 image. It sounds like your landlord may be sharing their TV service with the tenants, which is against Rogers terms of service.
The DTA only gets the channels that were formerly available in analogue format. If you want more channels than that, then you need a proper STB and if you want HD, you need an HD STB. If the landlord is charging rent, then he is account splitting, which is against Rogers terms of service. You should really be paying for your own Rogers service, unless the landlord has a corporate/MDU-type account.
They have to be, however, if the landlord is running a business, he should be a corporate/MDU-type customer. If he's simply a "normal" home-type customer, and if he's charging you rent, then he's account splitting. It happens a lot, but it's still against Rogers' terms of service.
