How do I parse idx and sub formats of video subtitle files in c#?
<p>I wrote an application that can read srd files well, but now I need to add support for idx and sub files too, how can I parse these formats?</p>

<p>Edit:<br/>
Later, I parse the srt files as <a href="http://www.codeproject.com/Articles/32834/Subtitle-Synchronization-with-C" rel="nofollow">this</a> article describes, I don't know regular expressions and now want to parse the idx and sub files.</p>
