Yeah, you're missing the fact that preroll doesn't solve the spun-down
harddrive case. Preroll only caches the first X bytes of data. If I don't
go to playing but let the harddrive spin down, it'll still take time to
spin up when more data from the file is requested.

Since I have no hard data, I can just restate: I have not ever seen
anything. Care to provide hard facts?

I was just interested in wether it does make sense. Afaics it still
doesn't, but feel free to implement it nonetheless.
