"Info" button causing freeze on Directv satellite service

About 2 months ago, delays began on all tvs when opting "Info" or using "Search." The only fix seemed to be doing a reset on the receiver(s.) I finally gave in & called for technical support and was scheduled for a service call after troubleshooting. The next day a Tech Support person called to troubleshoot (again) and after repeating all the steps advised that a new receiver would be shipped with the service call rescheduled as a backup in the event I could not connect and activate it myself while on the phone with Support. Thus far, Genie receiver has been replaced, I've spent a total of 7+ hours (I've timed all the calls, both theirs and mine) on the phone with multiple Tech Support agents, and now we still have the very same problem that initiated this mess - using the Info or Search options  prompts freeze to the service that lasts anywhere from 2-7 minutes. These are two options that we use constantly and the lack of their proper function is a real issue for us. It is not weather-related, all equipment is properly set, remotes are functional with new batteries, and this was never a problem previously. Last evening, I received a followup call to assist with connecting two of the mini units back to the internet. I was told one needed replacement and would be shipped and that any service call would be cancelled. The Tech Support people I have spoken with have been polite and professional but I am nearly certain they still do not understand what I am trying to convey - Info & Search just do not work properly on any of my tvs.  Any suggestions/remedies/moral support would be gratefully welcomed.
