When I playback my own 1080p60 (28 Mbps) video files with the GS7 the video's image and sound play smoothly BUT are de-synchronized. The sound is ahead of the image. Setting the synchronize feature in the GS7 menu from one end to the other does not change anything. The 1080p60 video files are on a USB memory key with other video files (AVCHD 1080i60 and MP4) which playback without any issues. The AVCHD 1080p60 files are the original in-camera .M2TS files shot with a Sony HX9V camera. The AVCHD 1080i60 files are edited .MTS files originally also shot with the Sony HX9V. The MP4 videos are .AVI files converted to MP4 with Handbrake. The GS7 is connected to the HDTV with a Sony High Speed HDMI cable. The TV is a 2 year old LG 47LD520 with the following specs (LG 47LD520: 47 inch Full High Definition 1080p 120Hz LCD TV | LG USA): Just Scan (1:1 Pixel Matching)... HDMI:1080p/1080i/720p, Component: 1080p/1080i/720p, RF: 1080i/720p 1080p Source Input... HDMI:60p/30p/24p, Component: 60p/30p/24p, RGB: 60p (WXGA) What do I need to do to have the 1080p60 videos playback without any issues like the 1080i60 and MP4 ones?
