I have a Pace DC758D Digital Box with no PVR Expander attached. It seems to keep loosing the Interactive Guide. All items in the Interactive Guide are listed as "To Be Announced". If I do a Box Reset by unplugging it, letting it sit for 30 seconds, then plug it back in, the Interactive Guide will reload after a period of time (about 1 hour), and things will be OK again for a while, but after a few days the Interactive Guide will revert back to the "To Be Announced" messages. I keep going through the reset process, and this does fix the issue for a few days, but then it comes back again. Having to repeat this process so often is really becoming a pain. Does anyone have any ideas on what may be causing this? What steps can I take to further investigate the problem?
