It isn't coming. It has been requested for YEARS starting right from when Optik was released. The older TelusTV (before Optik) had the feature.
Here's a suggestion: If you have the PVR, use it. That's what I do. You can fast forward through the commercials.
Auto Tune is a great feature. After having it with Bell ExpressVu for more than a decade, it's pretty tough to live without. Adding it to Optik Tv's software would be simple. The problem is, too few people are demanding it because too few people are aware of what it is. I've never spoken to anyone at Telus who had ever heard of such a thing or that didn't agree it would be great to have. I have no idea how Telus could ever be motivated to improve their service by adding it.
This is an ancient issue. The original TelusTV platform supported it. When everything was changed to the Microsoft Mediaroom platform (Optik), the feature did not follow. Microsoft had never implemented such a feature and never did until they sold Mediaroom. The new owner of it had not added that feature either and that's under the assumption it's possible with that software.
As for it being simple to add, it isn't or it would have been by now. Every change to the software costs a lot of money and time.
