DVR Response is SLOW

[NoLuck22]

I have two DVRs each in a separate room.  Issue 1:  When watch show in the room where DVR #1 is located, the show will jump 2-3 minutes to the end of the show immediately following FF through commercials.  I stop the FF just as the commercial ends, but the DVR proceeds to the end of the show without me being able to view it.  I then have to FF all the way through the show and watch the last series of commercials be able to see the end of the show.  I have two DVRs.  Technicians tell me the speed in the cables insie the house as adequate.  Please help;

What model DVR do you have?

BTW, if you have chaptering turned on, you can use the arrow to jump ahead by as much as 10 min at a time depending on the length of the show
