Hi, I hope you can help me. I have NEC ND4571 (with upgraded firmware thanks to ImgBurn link). I have (eventually) managed to compile all my bits of home video into a 6.2GB file, courtesy of ImgBurn, and burnt it to disc. After burning, I got error message about finalising. I pressed the Retry button and it finalised and verified no problem. Thing is, it won't play on any of my home DVD players, and is really glitchy with PowerDVD 6. I did NOT use Verbatim disc (I have read quite a few threads, and know how you love them), but would this cause this problem? As an aside, I used Nero 6 for all other burning, but having used ImgBurn, I am converted. I have ditched Nero altogether as even with firmware upgrade, it still wouldn't burn Dual Layer.
