Up until Tuesday I had an HR21-700 and a HR20-700. The HR21 was connected to the internet and the two boxes were connected via the whole home dvr package. Each HR receiver utilized a 1 tb external drive for recording purposes. The HR20 had been running slow for a while so I decided to call DTV and upgrade to the genie. The tech came out and the first genie he had would not recognize my access card when he entered it so, he left and returned with another box. This one worked fine although we had to reboot my wireless internet to get the boxes to once again recognize it and one another. All the tuners seemed to be working on the HR-34, the whole-home was working, everything seemed great. He left. That day, I sat down at the genie to watch something recorded on the external drive connected to my HR-21. All worked well until suddenly the genie stopped playing and I got a message that it was no longer communicating with the HR-21. Going into the whole home menu the receivers seemed to be no longer recognizing each other. This rectified itself shortly. This happened again 2 more times Tuesday. IT has not done it again in the last 24 hours so maybe it rectified itself or an internet issue although that would be a strange coincidence given I'd only had that issue with my old boxes twice in about 18 months and not once in the past 6-8 months. Than last night, I was again watching something from the HR-21 on the genie and suddenly the picture went black. I could fast fwd or rewind on the unit but I could not change channels or exit the playback function, I was stuck with a black screen with audio continuing to play. I turned the box off and back on but it remained locked on the pictureless recording. The turning on and off did however turn the hue of the screen blue. I finally did a red button reset. While it rebooted I went to the HR-21 and finished watching the recording, the recording itself was fine. After reboot the genie seemed ready to go again. Sorry for so many details but I'm not sure what might be important/unimportant with my issue. Does anyone have a clue what might be going on? Should I just call directv and try to get a tech out again or should I wait a while and see if the issue repeats itself. Any advice would be appreciated. I'm not very tech savy but hopefully was able to make the issue clear to those who are. Thank-you kindly in advance. Tom.
