Audio/Video Out of Sync

[Owen Smith]

I believe this approach is specifically to slow down get_iplayer's use of the network far below what would be considered it's reasonable share. This is based on a request someone made to be able to do this, base on an unsupported hypothesis that get_iplayer only fetches invalid chunks because it is fetching much faster than any real client.

I offer as a counter example the iPlayer built into my Humax HDR Fox T2 PVR. This fetches the programme absolutely as fast as it can, totally saturates my broadband link doing it, and saves it to file. It plays the programme from the file, and provided the fetch proceeds faster than the playback it doesn't stall. But it does nothing to stop the fetch getting way ahead of playback, which it does on my 79mbps downstream FTTC.

If I search for Linux traffic management or Windows traffic management I can see that there are programs which do that sort of thing, but they are only needed if I want to do clever things like running a heavily loaded server where the load has to be balanced between processes. I have 5 programs open on my task bar and 58 processes.  Windows allocates resources between them as they demand them without my even having to think about it, and has been doing a reasonable job of it since Windows 95.  Maybe you and David are doing clever things with your machines, but then I don't understand why you would run get_iplayer on the same machine.
