DVR 'resume' feature

In the past I have been able to begin watching a show on one TV then move to another location and complete watching the show from the other TV by selecting "resume" on the recording.  Lately this feature is seldom available and the only way I can NOW move from living room to bed room (for example) to finish watching a baseball game is to make a note of where the game is at time wize then fast forward to that point to continue watching.  Why is the resume feature no longer available?
