I noticed with some videos (& other files) it seems to downld sections that may represent different parts of the file not necessarily in chronological order of the video. I might be wrong but I suspect this is an issue with partial file sharing. Some bits are downlded as they become available but not necessarily the next bit in order. I don't know if that makes sense or whether that's the case but only my suspicion. Such as when you start to downld a file that's 700 MB in size, & immediately it takes up 700 MB of HDD space despite you may have only downlded a small portion of the file. The proggies will know whether this is anywhere near true or not.
