Does anyone have a download or know where I can get the DVD-X source code?

Sorry, no (I'm not a programmer), but if you mean the player that comes by default with Evo-X, then I'd love to see it recompiled with different joypad controls - it's a first class player, and it's only fault are the controls which aren't exactly intuitive.

If you do ever recompile the player, please consider changing the controls; the controls in XBMC's DVD player are ideal, and I'd really like DVD-X's controls to be the same as those.
