burning a dc hombrew game

i wanted to burn this hombrew game, its 3d pac-man but when i try to burn it with discjuggler, it says "the structure of the disc yo9u are burning appears to be invalid and could generate errors. would you like discjuggler to try and fix this?" i click yes but then it doesnt play on my DC.

That's right. You should've clicked "no".

when i click no it still doesnt work. though it has all been sorted out, i use alchohol 120% to burn theese types.

Then you should try alchohol 120%. 

There is ofcourse also a chance that the disc image is simply no good. That seems to happen surprisingly often.
