What I don't understand is how, for example, the Live At Wembley gig fits on a single DVD and it takes two CDs. I mean, I know DVDs can hold more than CDs but video footage and audio is surely more complicated than just audio? Can anyone explain this?

CD-Audio: roughly 1 megabyte/minute
A cd can contain 800 megs of audio, corresponding to about 79:58 in total
DVD-video/audio: roughly 30 megabyte/minute
Dual-layer DVD = 2x 4.7 = 9.4 GB = 9625MB
Divide by 20 --> 320 minutes, but only if you do not have more than one audio-stream, no extras, no menus, etc.
So the dual-layer thing is the main issue, plus the fact that DVD is naturally more roomy than cd.

Ah, I see. Thanks.

I thought that a dual-layer disk had a max of 8.5 gb, not the dubble of a single layer.
single-layer 4.7 gb
dual-layer 8.5 gb

im well cofussed.....
stupid question
And offcourse a CD can contain a lot data, but if you want to play it on your CD-player it can only play 80 minutes, so there stays a lot MB not used if you want to play it.
And most shows are like 2 hours, so it needs more than one CD.
