This has been going on quite awhile for me. I also know of 2 other people in my squad that this happens too.
Its a very intermittent thing also. I have no film, but I can start recording the next time im manning a gun. It may or may not happen.
But basically If Im manning a cv gun. OR Approaching an nme cv Theres a chance of being dicoed. Not just disco'd but the screen crashes to white, and i get the microsoft windows message do i want to send the bug report in. I'll try to get screens of everything. THis has been going on for me for about 3 years. Normally I just chock it up as a drag, I mean I really dont care that much how many kills I lost, or the bomber was discoed but It is a pain when I can't back into the arena I was in.
Anyway I'll try to get whatever info you would like to see, please let me know what I should I do to help you figure this out.
Also I normally never have any disco problems unless its on my end. Verizon is very stable, but maybe once a month they burp. And that disco is a host connection lost, not the same as the game crashing.
