1080p quality issues

Does anyone else have issues with WDTV Live displaying 1080p files?  When I try and view a 1080p i get a ton of ghosting, to the point where 720p files look significantly better despite the lower resolution.  

Is this a problem with the source files or an issue with the WDTV Live, or possibly an issue with my setup?  I’m hardwired network streaming from a NAS, and the connection appears to be good.  I get no stuttering, just ghosting / washed out video.

Anyone else experienced this?

Nope; likely has to do with your setup.

Any suggestions on what to check?

Check settings on TV. on WDTV and check the innards of your files using MediaInfo.

And, check HDMI cable, too.
