At the FIRST click on the "File I/O" tab, the "GPU" and "Quicktime" checkbox states from "Deprecated Features" tab are reset as the state they had at the dialog opening. Next, all is right.
A video tells more than words:
You just missed to click "Appliquer" before you switched the tab.
The problem appears to be that if you don’t click apply and switch to a different tab, then back again that the items 2,4,5 and 6 “stick”. But if you exit preferences and come back they are all now clear, so not applied.
When moving from one tab to another without OK or APPLY getting applied those 4 items check boxes are not being reset, only 1 & 3. Top to bottom = 1 to 6.
To summarise ... some radio buttons 2,4,5 and 6 visible states appear to “stick” when exiting the “tab control “, even though “apply/ok” was not selected. So it's just an appearance issue. These items are not really applied if you didn’t do so.
When exiting the tab control these 4 items need to be internally refreshed and set to “off”, in the same way that the items 1 & 3 are, when apply/ok IS NOT IMPLEMENTED.

Not exactly, to the File I/O tab only.
(i voluntary exit via the cancel (annuler) button for the video, to show the various cases of opening states.)
I had many such issues with preferences not sticking when I was setting up the VP17 preferences, not just with the Deprecated Features tab. Unfortunately I was unable to establish a pattern to the problem, but I wondered if it was because I had previous versions of Vegas open at the same time. I have eventually been able to make the preferences stick.
We have not seen this. I will have our team look to see if we can reproduce the problem and try to fix it.

In fact, without a Vegas proper closing, the Preferences and some other things like our customizations, are not really saved. So, if Vegas crashes, when restarting, everythings is at the same state that the previous launch. Annoying, for sure. Maybe your case.
