How to extend a recording

I know there’s been a lot of discussion about the program guide. After using the DVR feature, is there a way to easily extend a recording or record the show coming on next on the same channel?

For instance, I wanted to record the UFC fight but I figured it would go over its time slot so I wanted to record whatever show was going to come on next so I wouldn’t miss anything. This is going to be an issue with almost all sports. Unfortunately, I’ve not been able to figure out how to see shows in the guide in any chronological order by day.

What am I missing or any suggestions?

You can set a show to record past its end time in the advanced settings for that recording but having a real program guide with channels, dates, times, and schedules is something I miss having. Sometimes I’d much rather schedule recordings via a program guide instead of searching for the show name.
