Huh? The flv probe function only needs the first 10 bytes and the returns the
maximum score, any cache size should be good enough, and actually the stream buffer
should be enough as well - it just may be it is not used fully currently.
I won't accept any hacks for this until it is understood why they are needed, they
definitely should not be.
