### Provide a description that is worded well enough to be understood

When using the new Theater Complex extractor on a livestream/archive VOD, the beginning of the stream is not captured.

In the linked example streams, there is ~15 minutes of "bonus video" actor interviews, followed by a "stream begins soon" title card, followed by the main performance. Yt-dlp successfully downloads, but only from the start of the main performance section. It seems unable to grab the opening segment. This issue occurred both while trying to download live, and when trying to download the VOD after live streaming ended.
