I've been going to CONvergence since 2002 or 2003 and I can say with confidence that the only fanvid showing there was the one I arranged back in 2012. And you've got my playlist already, so you should be covered for that con. 👍🏻

FYI, I have paper programming guides for VVC 2005-2017 and for Vidukon 2013, 2016-2023. I also have Fanworks Con's 2019 guide. I don't have a scanner but I'd be happy to take photos of the vidshow listings in any of these for you if anything in the digital databases are missing or difficult to locate.

I have some digital PDF guides that list vidshows from the following:
Confabulation 2022
Fanworks 2022
Vidukon 2022, 2019
Escapade 2022
CON.TXT 2021

And a couple odds and from Wiscon:
PDF of the Wiscon 2017 Vid Party warnings list (with vids and vidders listed too)
Digital photo of the Wiscon 2019 Vid Party playlist

If you'd like copies of anything let me know! I'll dump them in a google drive for you.
