I have noticed that both of my DVRs (HR20 and HR21) are giving me a flashing "searching for signal" message on ESPN2 and only on ESPN2. When I run the system test, it tells me that my dish may need reaiming. When I test the signal meters, however, all are fine except for 99C. On that one, both tuners show as 80%, then tuner one drops off (acquiring signal) for a second, then it jumps back to 80% and tuner two drops off for a second. The upshot is that ESPN2 is unwatchable, but everything else is perfect. I am considering climbing up to mess with the dish, but I don't want to do that if the problem could be eleswhere. What should I do (bearing in mind that the MLL Championship is this weekend and I really need ESPN2!)?
