Here is my story, I switched from Dish to Directv in March. Three weeks later had signal issues on all my boxes ( 2 hr20 and 2 HR21) The tech then replaced all the barrel connectors. I found out at that time that the original installer used all my old cabling from my dish set up which was over 9 years old ( should have repleced all of it) at that time also replace my receiver in my living room kept going to 771 error. In June similar signal issue did a repoint and replaced to more barrel connectors. When Dtv went to MPEG 4 with espn and hbo I couldn't not get any of new mpeg 4 on any receivers. Trip # 4 tech said burned out wire between dish and switch and replaced switch and alll the wire drops. That brings us to today, I have one hr20 that will only get tuner one. I switched cables and still get only turner one. Tuner two doesn't work. Tech support had me do test and says tuner 2 0% signal and also says switch failure. Tech supports seems to think it is a switch problem again. I have been calm about this whole issue but 5 tech calls since March is getting to me. I really like the product but at some point enough is enough just fix it. Is this a common issue or am i just one of those unlucky few that have reoccurring issues. Thank you for any and all help and suggestions.
