Of course I wasn't suggesting to cache more than you can fit in a reasonable amount of memory, but if I had to guess I'd say that far, backward searches are less likely to cause issues? Anyway, maybe it's enough to cache the information on where to find the content (frames, a bit like how QuickTime handles reference tracks), rather than the content itself? > The problem seems to be down to the fact that some formats don't write the > header info > until the file is closed.

But you're not obliged to use that format, or support seeking in a format that doesn't support it (when there's the choice to use a format that does)?
