On my HR24-500 dvr the picture is freezing while the audio keeps going. This is happening randomly on different channels and it takes changing channels to fix it. I'm not having this problem on the H24-100 receiver in kitchen. I'm guessing this is caused by water seepage at the 8-port SWM, which is outside and we've gotten like three snowstorms in the past couple weeks. The SWM power supply is inline with the HR24. The unused ports on the SWM came capped with rubber seals.
