thx tcb2010.
I found the firmware n successfully upgraded. So far no changes that I've noticed and no description on what is fixed

The only hiccup pre-update was the flickering and color distortion once. I had to turn off the on to reset it. Happened after watching some avi from pc share manager folders then pressing return to menu. After update, been testing whole day to replicate it, so far so good. Not sure it's the update that fix it tho.
Al, could u recommend some so guides on calibration or explain what Chad B's post on page 10. Still new to all the terms like breaking in, IR etc. I'm interested in getting some settings. So far I googled some settings but warm 2 is too warm for my taste. White don't stay white anymore.
My setup -
Wall mount PS50C550G1R
Samsung B2330 monitor
PC with win 7 64bit
Running Ultramon utility to run double screen(great for running games on either screen) *** trial ending in 1 day

It works great but time for me to test MutiMon (free)
Wii
External Media Player with Hdmi output *for playing rmvb files etc.
A router
Media.P Mode - play supported videos/song in user folder *without PCSM*
- share folder with PC Share Manger (slightly more flexible in managing folders to watch) ** so far 1 hiccup pre-firmware update
Still hunting for a HT system while saving for it.
