I don't have IgniteTv, but if you can't control somebody else's set-top box, you still might be able to control somebody else's IgniteTv website streams.
I once had somebody remotely access my computer with the standard Windows remote access code that my computer generated. I gave him the code over the phone and watched him setup a sneaky DNS configuration in just a few minutes. If I had a Netflix subscription,, and he knew my login info, I assume he could also pick a movie, start the stream, and even adjust the volume of the stream.
If your mother had Rogers Internet, and a computer attached to the back of her TV (vja HDMI cord, etc.), you might then be able to go to the IgniteTV website, login, choose a channel to stream, and then even come back every few hours to press a button like pause (twice), to avoid the inactivity stoppage.
However, if the online streaming inactivity period is less than 4 or 5 hours, or keeps freezing due to a poor Internet connection, you would have to keep checking the quality of her live streams. But, if you stream On Demand or Recorded content, those streams should be easier to maintain a good-qualiity stream (similar to a streaming service company like Netflix, etc.) non-live stream.
Hower, all of this effort would be useless if streaming services block the remote-access codes, or they expire after a few hours. Plus, if the online inactivity stoppage is less han the 4 or 5 hours of the inactivity stoppage of IgniteTV, that would also make this effort annoying.
