Okay, so the file displays 25:47 in Media Player and plays... how long? Have you tried actually timing it, perhaps with a stopwatch like on your phone? I mean that is like a ~40 second difference if the number displayed is accurate I think you would be reporting some other issue, like being truncated, or sped up, skipping, etc.
