Here's the set up...I've got the onkyo 405 dvd player with hdmi and the samsung 88bd which is hd ready (upscaling to 720p/1080i). I purchased a hdmi cable from UKHDMI and connected the dvd player direct to the TV. I then have an optical cable running from the dvd player direct to the onkyo amp. Even with the hdmi cable I still seem to get wavy lines (if you look closely) on dark pictures/background and to be honest I'm not totally impressed with the picture. I was expecting something a lot better given that everyone is talking about the quality of hd. I used the settings on the v long 87/88 post but that didn't seem to make it improve much. Any ideas?
