Take the Rogers cable that comes from the wall outlet, and connect it to the cable in of the Free DTA adaptor that you receive, then connect the To TV connection to the RF or Cable in of your TV input card on your computer.
All you have to do now is put your TV tuner program onto channel 3, and use the cisco remote to change channels. Can't get any easier
The DTA is for people who are only on analog (no digital box), but want to be able to still view tv after the switch to pure digital. The DTA is free from any rogers store, (comes with the cisco remote, etc), but this will still only give you basic channels.
IF you want to view the TV, digital only specialy channels, etc... it would be pretty much teh same setup.
Out of wall into rogers digital box. Rogers digital box (via video cable or regular coax tv cable, depending on your ATI tuner).
Switch to the video input if in video connection, or channel 3 if on the coax connection, on your ATI software.
You should now see the output from the digital box. You HAVE to use the rogers digital remote to change channels, etc.. NOT the one with the ATI.
