Guide update registers multiple conflicting programs

[keith_leitch]

When there are last-minute changes to the program listings (which, in this part of the world, is frequent), my guide update registers both the original program times and the new program times. This has the effect of "doubling up" programs, both of which often record. Less frequently, it also has the effect of registering an incorrect program along with the more recent, correct one.

I was dealing with this by emptying the EPG before every update. However, this had the effect of losing my recurring recordings, as described here:

Does anyone know how to keep the older, outdated guide listings from appearing in the guide, and/or to prevent them from recording?
