I just returned from a 10 day vacation and started watching some of the new shows. One of my two HR10-250s recorded several shows with no audio. Both of the Heros recordings and a Law and Order SVU have no audio. I checked the audio settings on the HR10-250 and they are set properly. Both units have been running on 6.3d or 6.3e for about 9 months and this is the first problem I have seen. All my local HD channels are recorded OTA. Has anyone else seen audio problems on 6.3e? I restarted the failing unit. Any other suggestions?
