[Pkg-freevo-maint] Bug#529039: filter the TV guide

[Daniel Pocock]

Package: freevo
Severity: minor

The channels.conf that I generated from my new DVB-S receiver is 
enormous, and that is without even being subscribed to any paid channels.

In the freevo channel browser, with large TV-friendly fonts, it can be 
difficult to browse so many channels.

It is desirable to have all possible channels declared in the 
TV_CHANNELS config, but with a way of filtering them when browsing.  The 
user could be given a choice of filters:

- show only channels that are preferred for the user's region (i.e. if 
the user is in London, exclude the regional channels)
- show only channels for selected genres (e.g. movies, sports)
- show only channels for which a program guide is available
- show only channels that meet program guide criteria (e.g. showing a 
movie that starts within 2 hours)
- show only channels on a user-defined list

If the user could combine or customise multiple filters using their 
remote, or save a preferred customisation for re-use later, that would 
be really useful.
