White Lines at top of Recorded Video

[oddible]

I assume these are data lines for CC or something. Some of the other posts on this subject were pretty old. Wondering if there is something that has been done recently to add simple support for removing / adjusting for this in GBPVR playback of recorded video?

If I have to adjust Overscan settings to do this, where do I find these settings? GBPVR or in GeForce software?

Thanks.

OK, used F7 to cycle through the Overscan options and the one labelled 'Remove Letterbox' sets the video to correctly display without data lines.

Any documentation on what the values mean in the xml for overlay aspect?
