Petition for BBC HD quality improvement

A petition has appeared on the government's Number Ten web site calling for the BBC to sort out the PQ on BBC HD. It was not created by me but I've signed it as I think the BBC is failing its public, especially those with the reduced bitrate on satellite.

It can be found at http://petitions.number10.gov.uk/BBCHDPQ/
The Petition's purpose is stated as:

In August 2009 the BBC reduced the bandwidth allocated to BBC HD transmissions via satellite, resulting in a noticable drop in picture quality. Despite numerous complaints to the BBC by viewers, they have refused to even acknowledge there is a problem. It is widely believed that the reason for the reduction in bandwith is so that the forthcoming freeview HD channel which cannot achieve the same bandwidth as satellite does not suffer in comparison. However, the problem this creates is that the BBC HD is still compared to other broadcasters on satellite, and the BBC's own HD transmissions before August 2009, all of which are visibly superior to the current BBC HD channel in terms of picture quality. The BBC could overcome this and satisfy viewers by simply restoring the bandwidth allocated to BBC HD to the previous levels. However, the BBC appear reluctant to do this, but more frustratingly are unwilling to state why.

(There's a post on this over on Digital Spy, but it doesn't provide the link for the petition - I don't think DS like linking to external sites any more for some reason)
