If you had success submit the subtitles to a subtitle page.
If you did not have success:
Open your file with a text editor, does it look something like this?
15 00:05:48,357 --> 00:05:50,183 Nothing clean. Right.
16 00:05:50,317 --> 00:05:53,401 I think this guy's a couple of cans short of a six-pack.
17 00:05:53,528 --> 00:05:56,730 Your clothes, give them to me.
No? Sry you do not have a .srt file. There are other subtitle formats out there, maybe you can convert it to a .srt file. Go to divx-digest and find out how to solve your problem.
Yes it looks like that - it still does not work! Sorry I have not idea, go to divix-digest and ask the nice people there to help you.
