Even if you watch it for several minutes
OK, Upon further review, I believe they don't properly display exactly 59.94Hz.
Watching a 1080i channel, scrolling tickers will freeze for an eyeblink(one frame repeated?) every couple of minutes (not an exact timing, I know). Otherwise, it's buttery smooth.
This is with the Echo set to 'Native'.
On 720p channels, the video is as smooth as the 1080i channels, but scrolling tickers have a jitter about every second. It is not buttery smooth, but not too objectionable. Again, still set to 'Native'. While I can easily see the jitter on the scrolling ticker, there is no apparent jitter on the video; motion is smooth.
The odd thing is my TV only shows 1080p for the 1080i channels, and of course, 720p for the 720p channels.
No audio glitches for me so far. When changing channels, the video will stutter as it syncs to the audio, but the audio is clear.Edited by flipper59 - 12/20/12 at 1:01pm
