Need a tidbit of help for settings

[Misfit Fiend]

1. Recently i have made successful PS2 copies of: Crazy Taxi, Time Splitters, Silent Scope, and WinBack (all NTSC). I usually use CDRWin and Nero. However recently i've been trying to burn NHL 2001 (EA), i burn successful, but my copys won't work. I've tried swap tricks and all. Im running Gameshark v1.4, and i have a PS2
version 4, using the external USB NEO-Key. Any help would be appreciated.

2. Could someone also give me the burn settings for Fireburner? Im gonna start trying this one out.

3. Which is better recommended for Version 4 PS2 - USB Neo-Key or Internal Neo-Modchip. I have some customers to take of.
P.S.Sorry i don't read alot of the forums, but if anybody needs any further assistance, you can e-mail me. I've burned hundreds of PSX back-ups and several PS2's.
