Under the supervision of May and Taylor, numerous restoration projects have been under way involving Queen's lengthy audio and video catalogue. DVD releases of their 1986 Wembley concert (titled Live at Wembley Stadium), 1982 Milton Keynes concert (Queen on Fire – Live at the Bowl), and two Greatest Video Hits (Volumes 1 and 2, spanning the 1970s and 1980s) have seen the band's music remixed into 5.1 and DTS surround sound. So far, only two of the band's albums, A Night at the Opera and The Game, have been fully remixed into high-resolution multichannel surround on DVD-Audio. A Night at the Opera was re-released with some revised 5.1 mixes and accompanying videos in 2005 for the 30th anniversary of the album's original release (CD+DVD-Video set). In 2007, a Blu-ray edition of Queen's previously released concerts, Queen Rock Montreal & Live Aid, was released, marking their first project in 1080p HD.

The Burnside rules closely resembling American Football that were incorporated in 1903 by The ORFU, was an effort to distinguish it from a more rugby-oriented game. The Burnside Rules had teams reduced to 12 men per side, introduced the Snap-Back system, required the offensive team to gain 10 yards on three downs, eliminated the Throw-In from the sidelines, allowed only six men on the line, stated that all goals by kicking were to be worth two points and the opposition was to line up 10 yards from the defenders on all kicks. The rules were an attempt to standardize the rules throughout the country. The CIRFU, QRFU and CRU refused to adopt the new rules at first. Forward passes were not allowed in the Canadian game until 1929, and touchdowns, which had been five points, were increased to six points in 1956, in both cases several decades after the Americans had adopted the same changes. The primary differences between the Canadian and American games stem from rule changes that the American side of the border adopted but the Canadian side did not (originally, both sides had three downs, goal posts on the goal lines and unlimited forward motion, but the American side modified these rules and the Canadians did not). The Canadian field width was one rule that was not based on American rules, as the Canadian game played in wider fields and stadiums that were not as narrow as the American stadiums.

Which three Canadian football unions resisted the Burnside Rules?
Answer: CIRFU, QRFU and CRU
