Ouput Render overbright

Question

Hi,
I have been doing a few projects ovr the last few months, and have been having quite a bit of luck gettingout what I wanted to. Recently, I have had an issue where, whenever I Render out a clip, the resultant file, when played back in quicktime is extremely bright.
I pretty much work in a standard comp for all my projects:
16bpc
HDTV (Rec.709) 16-235
Linearize working space
I have some projects that i previously rendered, and what you see in the after effects project window, is basically what you get on render - untill now that is. When I render the project, i usually use:
Render settings - Best settings
Output module Quicktime with H264 codec
I now want to render out the best possible lossless versions for more work - I am doing this so I can interpret interlaced footage into progressinve footage for my workflow. This is something that i had chatted to Rick Gerard about and found his suggestion to inport the footage at 50FPS into a double frame rate comp. I then get discreet individual frames from the camera I am using. - But I say this just to explain why I want the best output for this part of the project.
Is there and obvious setting I am missing? ( I have reset the preferences via CMD+Option+Shift on startup of AE) - If I need to supply any more information, please let me know.
Thank you
Pierre

Hi Rick,
Thank you. I have checked that "Match Legacy Gamma" is selected, but the output render still remain rather brighter than it did. I am in the incredibly frustrating position, of knowing I changed 'something' as it worked fine a few days ago, but having no idea at all what that could be. After all these years as a Server Support Technician, I get to feel "The End-User" syndrome all over again....I will attach a screenshot of the project settings:
I ran some tests after reading your message, and you are absolutely right, but i still dont know why. I have a previous project, with all default project settings and that renders out fine. I change the project to the settings shown above, and the see the output below ( small section of outr one set with lots of shadows - Original on left)
The difference is very visible around the shadows - sorry for the little detail and small screenshot. Something has either corrupted, or changed "behind the scenes" As I'll attach one last example: Below, is a project I did a while back and the result rendered. I opened the same project now, made no changes, rendered a small selection out, and here is the difference.
Thanks for the help.
