I have a 4 tuner HD Homerun. So clashes of recordings are rare. But they do happen now and again.
I have a couple of suggestions:
1 - A UI for alerting the user to clashes that offers solutions to resolve the clash. For example, stop or start a recording a few seconds earlier or later. Or cancel a scheduled recording
2 - To help manage things, it would be good to have a visual representation of the scheduled recordings. I think of it as the same format as the guide, but only showing scheduled recordings. It would make it far easy to spot any issues at a glance
