A Feature All PVR's Should Totally Have

I was just ripping through the channels on my TV and caught a commercial for a show I was interested in watching, but was featured on a different network at a time 15 hours from now. Even worse, the show is available in HD, but to get there I have to jump 20-50 channels to find it.

There should be a "record the show featured on this commercial" button available to set up recording of any show being advertised, in HD if available, across channels.

This button has interesting possibilities across the many TV advertising contexts.
