I was going to make a longer post out of this, but since they've come up, I wanted to throw my hat in the ring re: the partials. Last night, I was watching the HR20 live at the genesis of what turned out to be a "partial" recording. One tuner was busy recording THE TONIGHT SHOW and I was channel surfing, parked on HBO-HD. At 11:58, a message came up asking if it was OK to change the channel to HDNet Movies to record TRUE CONFESSIONS at midnight. I selected "OK."btmoore said:That is what I would be doing, I would be wanting to rip through the header data from a few of these unwatchables. Based on my observations of the partial and unwatchable bug, I think they share a root cause. I wonder if you fix the unwatchable bug if it would fix the partial bug.
Two minutes later when the channel changed, I noticed the record light came on instantly, but the picture cycled through a second or so of black, then an all-grey screen and then locked in on the HDNet Movies feed. Perhaps the "partials" are due to the record mechanism not giving the tuner enough time to communicate with the multiswitch(es) and LNBs to change the channel? This would be right in line with what a lot of sports fans have been reporting about the Center Ice package, wherein if the feed is off at the start of recording or terminates before the end of recording, the recording will be listed as partial. Perhaps the HR20 assumes that if it doesn't have a signal within the first x milliseconds of a recording, it's not receiving the channel at all and the recording gets trashed?
I know this is the way the HR20 deals with recordings on channels you don't receive; for instance if you have an AUTORECORD wishlist setup by an actor's name or keyword, it will attempt to record on every channel possible, regardless of your custom list, and if it receives no signal the recording never appears in the Playlist and the history lists "partial." Thoughts?
