To be honest: if Cortado doesn't already allow seeking on already
downloaded byte ranges and is asking to re-download those, then I
think it's got a serious bug.

Where byte ranges are not downloaded yet, it should indeed do byte
range requests, but that doesn't seem to be what you are after...

Also: why are you using Cortado and not e.g. Firefox 4 with Ogg Theora support?
