I have a recent 50S60 and use Windows 7 as the DLNA server.
I noticed that videos that run perfectly on the computer have jerky motion and worse video quality when watching on my TV.
An MP4 file and WTV (Windows Media Center recording) files were fair, and an AVI and WMV files were unwatchable.
I am using network cables for both the TV and computer.
Are there settings that can be adjusted to improve motion and video quality when playing movies on the TV with DLNA?
