A feature I had often used on with some frequency on 'brand X' was being able to page back or refer referring to the prior day's guide data. I think it supported at least 24 hours in the past.
This was handy when something triggered the need for setting up a series pass on something I missed by paging back, selecting and setting it up, or resolving why something I had expected was not recorded.
Wondering if this is a simple feature to enable on ChannelsDVR where all the guide data goes poof as soon as it is in the past.
