Hello.

I'm sorry for my late reply. I had sent the same e-mail 4 days ago,
but the attachments were above the 80KB limit (which I didn't know
about).

Anyway, Thank you for your response. As for the time it might take, I'm content
as long as the issue is being taken care of :) .

I've attached both sub files, as well as the sub which was used as the
basis for the .ass sub in the pictures (It's based on the script of an
"opensource" fansub group called vegapunk). Please note that the SRT
file is not the same as the one I used for the pictures, as I can not
access that one right now. However it's for the same movie, and I
believe the results will be the same. The .ass file is exactly the
same as the one used for the tests :)

I've also uploaded a sample mkv file with both arabic and english subs
(49 Seconds, 20 MB) . Here's a link if you're interested in viewing
it: http://files-upload.com/283509/SMONEPIECE312HDTVRAW-001.mkv.html

Again, thank you for your interest :)
