New chunks are started too far into the file

[TheBlazingIcicle 0]

I think there may be an odd behaviour going on involving where it starts to download a chunk. It should do it from the leftmost position it can all things being equal, but i often see a weird creeping effect that appears to be caused by attempts on uses with no slots.

Has anyone else seen this by looking at the progress bar?

Its not a big issue, but it reduces the likelihood of being able to watch while its downloading.

No idea why its happening.

It also reminds me of a potential inefficiency that sources with no slots might cause. They will cause a $PSR to be sent saying that that chunk is being got, even if it isn't since they have no slots. Don't know if that's important enough to fix though.
