It would be nice to have the option to arrange your movies library based on what's coming up in the guide.
ie, you have a recorded Hallmark Christmas movie and that movie is set to re-run tomorrow night... The movie would be listed before other recordings that don't appear in the Guide data.
We have a lot of recordings and rarely watch live tv, so having an option like this would give us the option to see what "live" movies are currently re-running.
Not knocking your idea, but it made no sense to me on first reading it, now I think I understand.
In other words promote Movies you have recorded that are also now showing. Some new way of sorting them.
Are you trying to say if a Movie is going to show on a channel and you already have it recorded, show that recorded movie as a first choice to watch vs watching it Live or recording it again?
Sounds a lot like my TiVo's where it tells me such and such is airing or streaming, but here it is in your recordings already. Do you wanna pay to stream it or do you wanna watch your recording.
Ugh, grepping while distracted leads to cat - >/dev/null 2>&1
Exactly. 
It would just be nice to highlight movies you already recorded that are coming up in the guide.
My wife and I love watching the Hallmark Christmas movies and my wife ends up re-recording them all the time lol. At the moment, I bet we have like 3-4 copies of the same movie. & yes, I could go through and delete them, but that's efforting. 
Being able to sort movies based on what's showing/coming up would really help us decide what to watch.
