I tried to load a couple of backups (Super Mario Galaxy & Warioland Shake It!) on my Wii via the Backup Launcher 0.3gamma, and they boot successfully, and the gameplay is smooth, but whenever there's a short movie that starts playing, the video is very choppy and if there's dialogue, the voices are choppy as well. I am using the Disk Utility in Mac OS Leopard to burn the ISOs. I've tried it at 8x and 4x (it's the only 2 options available for burn speed). Would it be the type of DVDs I use (I use Memorex DVD-Rs, single layer), or it's just because I should be using Nero in Windows to burn my ISOs? p.s. if it's just because I should use Nero, is there a free alternative to Nero? thanks!
