Did they just start working or did you reboot in between?
It just started working.
In the DVR status page in diags, what is the "# of trash empties"?
Was the SD recording digital or analog?
It was analog. And it was being recorded as we watched a HD channel and used the pause as I recall.
Did the reboot solve it? Did you have HD content on both tuners? Were you looking at live video?
So far its OK. Haven't watched anything just took a glance.
I was watching live and more than likely had HD on other tuner but can't be sure.
( Just looked again and Planet Earth episode was recording and macroblocking the other tuner was tuned to the same HD channel as the recording so I changed it to SD digital and it seems to clear it up so far except I have no audio now. The only way to get it back is to shut down DVR turn it back on and than it comes back. So I can't have both tuners on HD?
Is this new behavior? Does it happen when changing all channels or just certain type of channels (i.e. analog to HD or HD or SD)?
No. its not new but it happens more often with this latest box. It did on about 5 HD channels (HD to HD) a little while ago and then one SD to SD on digital channel. And then when I was in Diags looking at number of trash empties it popped loudly three times about 5 seconds apart after I was back at the computer. And then it was fine for the rest of the time. I've checked connections and everything seems fine. I am using the optical audio connection and component and HDMI and neither seems any better or worse.
