burning problems

I'm having trouble burning Sonic Adventure. I'm using Nero 5.5.9.9 Normal version, burning on Memorex CD-Rs at 52x, Disc-At-Once. The game is selfbooting, but doesn't load, so I tried Utopia.....still doesn't work. I attempted Track-At-Once and Disc-At-Once/96. I got the game to work on a different Dreamcast at DAO, but it won't work on mine. My Dreamcast was manufactured in June 2000 and several other games that I have burned have worked just fine. Any help would be greatly appreciated.

You'll find the original version of the game will not only boot straight away for you but it'll hardly cost you anything.

No support for warez - read the rules, locked (for obvious reasons).
