meh... well. I hate to tell you this, but just in case you didn't know. To use burned images of games on your console, you need to have the console chipped so that it accepts those specific DVDs and stuff.
Check out Mod-Chip.com or Modchip.com for more info regarding this. You can get hardware here, which you can install without opening your console if you want, but they arn't as effective as the chips and may not work all the time.
EG:
For the chip: MAGIC V for all V5-V10 PS2 consoles
It states:
</div><table border='0' align='center' width='95%' cellpadding='3' cellspacing='1'><tr><td>QUOTE </td></tr><tr><td id='QUOTE'>The Magic V ModChip allows you to boot any PS2 or PS1 Import and Backup Game (CD-R, DVD+/-R) without swap method and without the help of an Action Replay 2 or Gameshark 2.</td></tr></table><div class='postcolor'>
The swap method btw, is where you put an original game in, with the lock (located under your PS2 CD Tray) on the top of the game and load it. As it loads you quickly take it out and put the burned version in. I wouldn't recommend this method though. As for the other method concerning the Action Replay or GameShark, i don't know that method.
Anyway. As for burning them onto the DVDs. Refer to your chip/part to see what formats it supports.
