Panasonic Viera TV artifacts

older Panasonic TV's like the TX-55ASX759 also known as ASW754 need a lower threshold if there are artifacts during normal play, here I need "-H5:50" with a LAN delay of 4ms due the Ethernet uplink via MOCA 2.0 adapters. you can also try with a different buffer size like -b 13160:5775360
