Please also note that 'if' has a return value in Ruby.
See http://www.rubycentral.com/book/tut_expressions.html#UH for reference.

So your code could be written as:

   # now find the current program for this
   # channel.
   programsForChannel.find { |program|
     if program.time <= showTime
       if program.endTime
         # there is a endtime.
         # true if we now are before this end
         true if program.endTime > showTime
       else
         # program has no registered
         # end.
         true
       end
     end
   }
