Make sure you're burning the ISO properly with imgburn. Either associate the file type with imgburn so double-clicking it causes imgburn to open, or do a file>open with imgburn. Burn at 4x or 8x and select the "verify" option in imgburn so it will check if the burn is valid.
well i tried it again using a friend's hp laptop. same blank type of dvd-r. worked just fine. originally i burned using my macbook.
so... if anyone is having trouble getting this to work burning with your mac, try it on a pc. worked for me...
