Unfortunately, this feature

Unfortunately, this feature doesn’t exist in WMC.

Many moons ago when I had Dish Network, their DVR did have this feature and at the time, my wife and I sometimes found it useful. Over time though, the feature became much less useful to the point that my wife and I never needed it because we completely transformed our viewing from a world of live TV (and commercials) to one where everything is recorded prior to viewing.

Perhaps you can overlook this deficiency in favor of all the other functionality that WMC will give you over the terrible experience you currently suffer from with the cable DVR.
