i have a lot of subtitles that need to be converted to another framerate (they go out of sync gradually), but subtitle workshop doesn't automatically detect framerate of opened subtitle. is there any software that can do this?

What kind of subtitles? Some subtitles are frame number based, some are time based.

SRT has no frame rate. It uses timestamps. Probably the best thing to do is look at the last subtitle and locate the corresponding time in the movie. Then use the stretch function in Subtitle Workshop to adjust the timing.

IDX/SUB? I don't deal much with those but I suspect the same method will work. The IDX file is plain text. You can edit it with Notepad.

There's a plain-text .sub format, too. I've never really dealt with it, and don't have any subtitle files around I could convert to .sub just to take a look at the format, but I think this is probably it: http://en.wikipedia.org/wiki/MicroDVD

That one does appear to be frame-based.
