I have been using the Paterson Tech TV translators for years now with my ReplayTV's without any issues at all. However, a while back I started seeing channel change failures on 3 of my setups (1-H20 and 2-H21) which caused the wrong programs to be recorded. This was in the same time frame where a software update to the DTV receivers was pushed, and caused extremely slow receiver response times. After a week or two, the H21's started working again. This was about the same time as the software update to resolve the slow receiver issue was pushed. I cannot say for sure that the channel change failure issues appeared exactly with those software pushes, but I do remember that it was not a fun time in the house where out of 5 DVR's in the house, the 3 Replay's recorded the wrong thing, and the 2 DTV DVR's (HR21's) were slow as mollasses. But after all of that, the H20 never started to work right. Resetting or unplugging and plugging the H20 back in was the only way to get things working again, but after a day or so, the problem returned. So I had DTV swap out the H20, and they gave me an H24. Yippee, I thought. Surely, this new receiver will solve the problems since the H21's are working just fine. However, the H24 shows the exact same problem as the H20. I can reset the receiver and things work just fine, but after about a day, it's like the H24 just ignores the rs232 commands. I have already verified with Paterson, the setting needed to control the H24, but that still doesn't resolve the issue. I have moved the H24 to all 3 different setups in the house, and the problem follows the H24, so it is not the Replay's or the translators. Software versions on the receivers are: H21 - 0x44c4 H24 - 0x4c4 So, does anyone else seeing anything like this other than me? Am I going mad? TIA, J P.S. Please don't recommend that I upgrade to a DTV DVR. Already have 2 in the house. The Replay's are for the kids and they have massive amounts of archived recordings that would get lost if the Replay's are taken, so not an option.
