Black Level Variations
A lot of this is the varying versions of HDMI. It is in a word a mess.
Then MS, Cyberlink, ATI and Nvidia all have to integrate (play nicely) together.
Frequently they don't.
I always set my display and ATI drivers to 16-235 range, so that everyone will know this is what I want. Do they listen? Sometimes yes, sometimes no.
For instance, the current Power DVD 10 I have to change the display to full range(0-255) to get the black level correct, else it too dark on two of my three systems.
On the third (an all HDMI 1.4) system, it works fine. Why? HDMI "smart" reporting is often flawed between components and generations of the specifications.
The solution is easy: upgrade your HDMI gear each year. Throw the old stuff in the trash. Great for high-tech employment.
WMC 7 black level now stays correct. The ATI drivers don't smear motion anymore at 24Hz. So great progress is being made by many bright people.
Frame Rate Selection
I hear in 2023 they will switch between 24 and 60Hz automatically, just like them stand-alone players. Obviously a grand scheme get a promotion or doctoral degree.
Horizontal Smearing Gone
Noticed a huge reduction in horizontal Motion Smearing on my systems with the latest ATI drivers with the new control center. I confess to loving Ponyo (24hz) a very high quality animated Japanese movie. There is a scene where the mother pulls up to the nursing home. In the old days (last week) the ATI drivers would smear and jerk the building's trailing roof. My Panasonic VT25 really does now have much less smearing (as they advertise with the low delay phosphors). Congratulations!
ATI Control Center
view is a step forward resulting is less mouse navigation. Congratulations again!
Streaming Issues Updated
One of the first steps is to establish a clean baseline by reinstalling the latest Ethernet drivers from Windows Device Manager. Do this for all computers on the network.
Realtek drivers are here:http://www.realtek.com/downloads/dow...&GetDown=false
Leave everything default except for MTU which I set to 9K, cause were streaming. Other settings (like off-loading) are pretty dangerous, and can choke your streaming. Ridiculous but true.
Then, with Windows Task Manager->networking->network utilization monitoring, copy video files between computer desktops. For Gigabit Ethernet you should see 80-90MB/sec (9*8 = 720Mbits/sec).
