Are you a Comcast subscriber? Do you use the Xfinity app on your iPhone or iPad?
There is a new update to make this app more efficient. The update is significant because it adds integrated DVR management. The DVR management will allow you to modify recordings as well as scheduled new recordings.
You can also use this app to manage the priority of your recordings. This would be helpful when a new show that is just starting you want to see more than one of your old shows at the same time conflicts.
You can get the update on iTunes.
