DVR Cuts off End of Show ...

I tried searching on this (probably common) issue in the forums, but could not find answers.Hopefully someone here has a solution.

I just got Cox + DVR (after years of having DirecTV DVR and Comcast DVR) - and those prior DVRs seem to have the problem solved for recording shows that "go over" their scheduled ending time by a minute or so. And even better, those DVRs seem to even know when an entire show has played later due to some other event (ie - a football game running late).

AnywayI just got Cox, and have been recording Jeopardy, as a scheduled series ... and consistently the DVR cuts off the last minute or so (the most important part!!). So how do i prevent this from happening? And this question is more for recording as a series (so I cannot program the recording time for each show).

Suggestions?

Thanks!
