Are there any DVD loaders that will run from memory card?

That don't need a TOC refresh?

I wanted one to run PS2 MediaPlayer.

Also is there some frontend menu I can use to put multiple emus on one DVD, that has a return to menu function (can't reset with a DVD-R, :) )

no return to menu function, as it would need to be implemented in the emulators themselves, but you could easily put LaunchELF onto your DVD, and use it to boot the emu of your choice.

Alright, thanks, but is there any way/program to put on the memory card to load the DVD itself without using a swapdisc? I can do this with CD-Rs, but not DVDs...
