dvd-freak: I like the idea very much.
As your concept is a scheduler service, I think this could be used to create an EPG with all the shows of your interest.
Personally, I donīt like to record everything that might be of interest, but I would like to see (and not miss) the information about interesting shows.
1,5 years ago I proposed a personal EPG idea and developped it further with Bavarian and ideas from the forum:
The link below is not the alpha version, but the thread where the concept was discussed:
[New: Alpha version] A learning personal EPG
There you will find a lot about the conceptional ideas. I think you know the alpha version, which was able to define some rules (similar to yours).
In addition you could score the importance with a 5 star system.
The final idea was to make a database about all the shows you viewed (for longer than 10 minutes or so), recorded or manually added as favourites in order to create a personal epg based on your viewing habits.
Bavarian often stated, that he is still working on it from time to time, but he is doing a lot of other things for MP too, so I am not sure what the status is.
Maybe there are some ideas in the concept that are of use for you. Well, considering your service for an epg with interesting shows was the main point i wanted to make.
Maybe the recordings and not recorded but shows of interest could be close together by adding an option to the rules automatic record yes/no.
