How do I disable / delete video overlay?

[pcGnome]

Most never notice this and it seems to be an artifact from when video needed special handling to get quality / speed better.
.
My problem is that as I get older and my eyesight starts failing, I've been relying more and more on Magnifyer.
.
But guess what? Magnifier CANNOT see video that is using overlay. it's just black.
.
My fix works, but I should just be able to disable it altogether.
.
Step one: play a video I'm not going to watch to take over the overlay and minimize it.
.
Step two: play any video I want and it shows up in magnifier just fine.
.
Any ideas?

Use a player like VLC that supports Windows GDI as the video output device.

Well, now that VLC is the only player that I can get to play x265, I may have to give it some serious thought. If only ALL the commands in MPC worked in VLC, I'd be a happy camper.
.
So, no suggestion for making MPC obey this Windows GDI thingy?
.
I think overlay is video card supported and that probably makes it ATI (Okay, AMD) supported. Should be a feature that can be turned off.
.
Oddly, to keep my video files with their own icons in Win7, I use different renamings and file associations for each video type (also use resource hacker to imbed the desired icon into each different MPC.exe). I only mention this as the AVI version never uses overlay, while the MKV version always does. I'm thinking maybe the video renderer I'm using is somehow configured differently. Maybe some use this GDI thing while others don't (have ffdshow, halli, LAV, etc ...)
.
Anyway, not a huge problem, but thanks for some insight into 'output device' possibilities.

Try the different output devices in MPC. It doesn't have Windows GDI though.
