It sounds like you know more about Fraps and Dxtory than I do so I won't be able to help. I did do some testing though. When using Dxtory with both ENB and SKSE I get a crash. When I disable ENB and leave Dxtory and SKSE active the game loads up normally. I haven't tried uninstalling SKSE and then using ENB with Dxtory since you already tried it, but it seems there's some kind of conflict when you use all three programs together.
I'm not sure how Gopher is getting it to work. I read a comment on one of his videos on Youtube where he said he was using a hardware recorder now instead of Dxtory, but he didn't say the reason why. Perhaps this is the reason. If you want to see the comment it's at the very top of the comments on his latest ENB video on Youtube. Here's the link:
Edit: The comment is no longer at the top of the comment section but you can still find it if you look through them.
