Thanks, guys!

I added an additional title I missed (Midnight Horror Collection Vol. 6: Passed the Door of Darkness).

Looks like there is also a single dvd release of "Passed the Door of Darkness". Then everything gets grouped into those Midnight Horror Collections. I'm looking at the back solo cover on dvdempire right now and that says Micheal, but I know we need the film credits. If I see that for cheap around here (shipping would be too much to pay ) I'll grab it and audit it, maybe watch it too! Looks like it could be okay, or really bad.

Screamplay : not credited

NCIS: Naval Criminal Investigative Service: Season 9, Episode 3

I wouldn't bother unless you really want to see it. No use wasting money for a common name thread.

EDIT: Looks like I bungled the credit for Buffy: Season 4.  I was so focused on the spelling of of "Michael" that I didn't see they also spelled his last name as "Conner". I plugged that into the CLT and it came up with an additional result for Studio 60 on the Sunset Strip. I just streamed it on Amazon and the credit is "James Michael Connor".
