OK, it's quite choppy right now.
I pressed pause and then play again, which is running on recording. There does appear to be a little pixelation on the recording, but no picture breakup.
I checked signal strength on tuner 1 and it's 98%, with quality 100%, and very little variation.
I'm not tuned into anything other than my usual transmitter, and it's running on its usual power.
Powering down and back up and its now 100% fine.
I don't mind doing this occasionally, but this is now becoming an annoyance.
It's a shame there is not a suitable replacement that is not bug ridden as the 5000t was a bad decision on my part. All previous Humax boxes i've owned have been much better.
