i installed the hd service yesterday, all channels output proper signal, but what confuses me is on my rogers remote i can zoom in, when this occurs it changes into 1080i!on any channel!although it does look distorted when on a non-HD channel, just what exactly is happening how is this possible ?

2. Also my LCD has a resolution sensor it indicates im getting a 1080i signal!HOw is that possible if my LCD is supposed to be 720p maximum?!

Although that is what the salesman told me at the BRICK and the lcd was on display with 720p written in bold

specifications appreciated thankyou in advance
MERRY CHRISTMAS
