The decsion to leave out the centre channel was made by Brian May and sound enginner Justin Shirley-Smith.
They felt the natural front L & R soundstage was more true to the vocals than with them coming out of the centre speaker!
I still thought it sounded good though.
As for the aspect ratio.......WELL!
This has to be one of the most bizarre and abusive use of anamorphic 16:9 that I have ever seen on a DVD.
They've used every technique in the book and even made one up themselves.
Here are some screen grabs to explain better....
(These are exactly how you would see them on a WS TV in it's anamorpic wide mode)
A KIND OF MAGIC
Fat Fred!!
Stretched 4:3. Not sure if this was intentional or they just forgot to remove the WS flag. Easily rectified by manually overriding the TVs AR to 4:3.
What's strange is, the video was made in approx 1.66:1 so they had room to do a decent conversion here, but opted to simply stretch it horizontally instead
RADIO GA GA #1
This is an original 4:3 image in a 16:9 window, much like they do when showing foreign footy on UK TV where they use coloured vertical bars (aka 'pillar boxing')
RADIO GA GA #2 (Chorus)
Same song but now the image fills the 16:9 frame, much like reverting back to the studio in the footy comparison above.
IMO, this is the best of the bunch and they've been really clever with this one as the video was made in 4:3 but the choruses used a sort of 'Squashed WS effect'. So they removed that effect and use a full natural looking WS image instead. EXCELLENT.
INVISIBLE MAN
Original 4:3 left intact.
I've no idea why this video alone was left in 4:3 OAR.
HAMMER TO FALL
THIN FRED!

BIZZARE to say the least.
I have no idea what they have done here and why.
Bear in mind the original video was shot in 4:3.
They seem to have stretched it horizontally x1 and vertically x 2!!
Why not simply crop it to 16:9 like they did with most of the others?
I'm pretty convinced that this along with Magic is a technical error and would even warrant a recall (ala BTTF).
The other videos fair pretty well and three of them were actually made in WS (I Want It All, Hard Life and Princes), but they would have been better off leaving them ALL in 4:3 OAR rather than try and put 'square pegs inton round holes', as they have clearly struggled with some and it shows hideously!
All in all a big improvement on Hits 1 but not in the same league as WWRY or Wembley.
