Rogers quietly seems to have added ToonAVision, but the channel is not on the guide, cannot be recorded, paused, rewind, etc. It is found in the Apps section under Entertainment.
I really disapprove of channels being replaced with apps. This should be added to the regular guide, probably in the low 200s with the other kids channels.
Other than cost.
Like many of the other apps added lately, they are generally 'free to watch' streaming services.. which mean that in general there is no licensing fees, etc around the content.. the end user is allowed to watch pretty much not strings attached.
Now in the case of TV.. generally there is licensing fee's around that, to be able to provide it on TV. Rogers might have to pay a fee to get a channel added.. vs probably pretty much free to add the app.
The issue with those type of (cable box) apps, is that those of us that usually use web version of IgniteTV (desktop/laptop) or tablet/phone version of IgniteTV, don't have access to the cable box app unless we actually turn on the TV and use the cable box.
One way to fix that would be to have (in this case) ToonAVision to have a provider login system with the video catalog on there website.
