Hardcoding Subtitles in MP4 not working. Megui/VSFilter/Avisynth.

[Rez.]

Hello all.
I've been trying to hard code subtitles into a movie for the past few days using a combination of Megui, Avisynth and VSFilter but with no luck. The resulting movie does not have the supplied subtitles burned into it. The subs are in ass format if that matters. I've tried several versions of VSFilter now. The one that came with megui (Located in the megui's avisnth tools folder), I have downloaded and installed both VSFilter and Vobsub ( Making sure to point my avisynth script to the correct VSFilter.dll each time) But still nothing.

I have included my Avisynth script in the hope that maybe I have screwed up somewhere (Wouldn't surprise me ). If anyone could point me in the right direction I'd appreciate it.

Thanks for reading.

Open the script for testing in VDub(Mod). Does it open? Do you see subs?
