I have a number of videos on the Live Hub Media Center internal drive that the playback is very jumpy. The video pauses about every second. The audio is fine. The same video file when on a PC and other media players plays fine. What could be causing this to happen on the Live Hub? The Live Hub is fully up-to-date on firmware. Thanks.

First things first…you need to be aware that although a file plays fine on your PC or other devices it might not meet the encoding requirements for the Hub. You need a PC program MEDIAINFO to look at how the file is encoded and compare that info to how it SHOULD be encoded for the Hub. I have a hard time understanding it all myself but if you use mediainfo you can cut/paste the info here and I’m sure someone (TonyPh12345 or JoeySmyth) in the know will look it over and see what the problem might be.
Below is a cut from Page 217 of the Hub’s manual:

Hope you can sort it out!
And … after installing “MediaInfo”

Sometimes when I get a problem like this just tweaking the video settings from 1080p to 1080i lets the file play stutter free.
Is the video you’re trying to play a ISO image? If so try turning off DLNA in WD settings and see what happens. If it isn’t that then are you playing the video at the same time you are muxing or copying stuff on the same HDD you’re playing it from? As doing that will congest the HDD and cause the video to lag.
