Yeah my fix only works when using True Motion, I should have mentioned that. I intend to make it work all the time but it needs more code, it's on my to-do list along with other AviSynth improvements
I've had problems with HorribleSubs releases because they use weird framerates like 23.810fps even though their sources are 23.976fps, no idea why they do it. It might have something to do with why it isn't working, though I can't think of why at the moment.
Please try it again and then paste here the contents of "C:\Users\Admin\AppData\Local\Temp\ps3mediaserver\pms-avs-[HorribleSubs] Fairy Tail - 126 [1080p].mkv.avs"
