X1 not recording all of my Sunday shows due to football

I used to be able to set my receiver to record for up to 1 hour after TV show scheduled ending.  Now I can only record for up to 30 minutes.  As a consequence I miss the end of every tv show I record on Sunday nights.  Can I get my option to record for extra hour back or can you actually record  tv shows when they air and  not when they are scheduled?
