Advertisements I have a Roamio Pro and two Mini’s in combination with a Motorola tuning adapter. That said, I have a strange issue with tuning SDV channels (only on the Mini’s) whereby I am often greeted with a V53 error on the first tune and must retune the failed channel a second time which usually works. Logic would dictate that it must be a TA issue or a signal problem on my end, however I never experience this on the host Roamio, only on the Mini’s. Even more odd is that once I finally tune an SDV channel on the Mini, switch to another channel for a few minutes, then return back to the previously tuned SDV channel, I often get another V53 error and again must retune the same channel. Also, I never miss any recordings on SDV channels so this suggests to me that there is a difference in how SDV channels are actually tuned through the Mini’s versus the host. Has anyone else experienced this?
