Advertisements After 3.5 years of mostly trouble free operation on our Roamio Plus, we've started experiencing a recording issue in the last week or so. We are with Spectrum (formerly Brighthouse) and still have the original BH M-card and Cisco STA1520 tuning adapters. We also have a Roamio Basic in another room for the kids with the same type of M-card and TA but there's been no drama with that one. About once a month, I power cycle the TA's for both as preventative maintenance. Until now, the Roamio Plus has operated just fine along with the Mini connected to it. The only prior issue with the Roamio Plus is that sometimes when I cycle through the 6 tuners, one or two tuners will display black and I have to press select to tune the channel again. This mostly happens with upper tier and premium channels. Not sure why that happens but it wasn't affecting any recordings so I ignored it. Although now it might have been an early sign of the current issue. So now to the present issue - for some onepasses, scheduled recordings start but only the first minute or two is recorded. Mostly this has happened on ABC but it also happened on NBC and HBO once or twice. History manager does not show any event so it seems as far as TiVo is concerned the recording was successful. Other recordings worked fine so there didn't seem to be a consistent channel or show this happens with. First time we noticed this , I restarted the Roamio and TA but the issue happened again a few days later in between days of successful recordings. Last night, I was able to observe the beginning of a scheduled recording that failed and noticed some odd behavior. The recording started on schedule but a minute and 10 seconds in the recording stopped, a brief black screen and live TV played with the buffer. I had to go into the guide to start recording again (wouldn't work from live TV with record button) and then it only recorded the first minute again. I noticed then that when the recording would be interrupted that the tuning adapter would blink a few times and the screen with go black for a moment. I also noticed at least once a grey box popup on screen that said updating channels with a progress bar. While I did not note the channels, the other tuners were on other random channels (probably due to suggestions recording). I rebooted both the TiVo and TA and left the TA unconnected at first and the recording worked fine (it was on ABC). I connected the TA after 20 minutes and the recording continue with no issue. At this time, all the tuners were on the same channel (ABC) thanks to the reboot. About 30 minutes later, three other shows started to record on schedule and had no issue (one was AMC and another HBO and the third on PBS). At first I suspected the TA since it started blinking when the recording stopped and then the grey box with updating channels message but perhaps that is normal behavior if the TiVo has a hiccup and stops communicating with it. I am not sure if the channel I was trying to record is the issue or perhaps a different channel tuned in on another tuner that triggered something. Hoping for some advice on how to troubleshoot since the issue is intermittent. For what it's worth, after the first recording stopped, I set all four scheduled shows to record on the Roamio Basic with the same type of equipment and those all recorded without issue.
