PPCER

Go to ImgBurm / Tools / Automatic Write speed. At the bottom of the page it has Settings / Disc ID. I don't know what to type in. Is it looking for region, Disc mfg etc? I'm in the USA, and I think that's region 1. The reason I'm trying to set this up is because, while burning a movie it shows MAX speed and it generally burns at 15+mb. I'd like to get it down to 8 or 10. Under Disc ID it has the speed. I've been installing 8 but it runs MAX. Any help would be appreciated. Thanks
