Splitting .OGG files in two

[Durran]

Since I've downloaded some Anime from a group which puts 18 seconds of useless media at the beginning of their encodes, I want to remove all of it. I know how to use AVI splitter to split the AVI, but how would I split the .OGG audio files? I see a topic called "OGG / OGM Creation and Cutting Guide" stickied but the link it refers to seems to be down so that's not really helpful. One other thing, is there an easy way to modify the srt so all the timings will be set back 18 seconds? Thanks in advance.

Oh, one other thing. The .SRT format looks like this...

00:00:33,795 --> 00:00:38,164

... but what are the numbers after the commas for?

search for OggCut.

srt timing format:
hh:mm:ss,xxx
xxx = milliseconds
you can use subrip to modify the timing.
