I've had this long-standing issue where cutscenes can get really choppy with terrible audio when playing Wii games on USB Loader GX. It's especially bad for Super Mario Galaxy. I'm playing the games off of a FAT32 formatted external hard drive on my vWii. I've found a few threads and posts about this issue, but nothing that's helped unfortunately. I'm not really sure where to even start with trying to resolve this issue. Any ideas?
