That is exactly why I don't want to release it, I don't want to release something if I can't even use it myself. And I never even figured out how to get it to work without ENBSeries properly.
In regards to the animated menu not working with enbseries...
Looks like the enbseries problem is with a crash in quartz.dll when using enbseries d3d9.dll (any of the gtasa ones - 0074 series or 0075 series).
I don't think quartz.dll can be replaced in windows without going into safe mode (haven't tried that), and it doesn't seem to get recognized by placing it directly in the morrowind dir with d3d9.dll. Replacing quartz.dll may not be the best solution tho - it's part of directx and should be upgraded/downgraded along with the rest of that package.
FYI: I'm using directx v9.0c Nov2008 redistributable (4.09.000.0904).
As far as trying to get the menu to work without enbseries:
Have you tried encoding to an mpeg format, then renaming the video with .avi extension?
Download Fliggerty's Christmas_Club.mpg or Halloween_Club.mpg and rename them as .avi - both are widescreen format and I used them as tests for this method; they play correctly in-game with the game menu displayed over the video and selectable.
