Yeah I think you can make a disc with a different format on each side, though dual-sided DVDs alone used to have problems so it might not work very well. It would probably be better if they'd just put 2 discs in the pack.
are you talking about HD DVD/DVD combo disc? yes it's possible..because they already exists. I saw Superman Returns on sale that is a combo format
but if you are talking about a HDDVD or Blue Ray disc of that concert... keep dreaming
if they filmed the concert on film (like Montreal 81 or Budapest 86) yes they could do that. but if the original source is video tape (like Wembley or Milton Keynes) the answer is no. there is absolutly no point in releasing a high defenition disc with video taped sourced material.
ps: Brian sayd a some months ago that Budapest was is choice for the next Queen live DVD... and i can add, i hope that Budapest is the first high defenition disc release of a Queen concert
Yeah. I was bored when I made that image.
I liked the result though, cos the red cover fits the design of the HD DVD cases (being red themselves)
Now if I could make a Blu-Ray cover of Wembley '86 :P
