I believe there is a BUG in Hopper 3. All the recording stop times are inaccurate, not just sports. Besides the programs stopping to record before the end of the program, the playback is broken. If you pause prerecorded program and then hit the slow forward button, playback starts at least 30 seconds to a minute later then where you paused. Very disappointing, nothing to do with guide settling down. I had this for 4 month now.
I was told by Customer Support this is a know issue and engineering is working on a solution. It has been a long time so if anyone else notices this, please post here. This is a huge problem for me. Worth returning the Hopper3. F
