Hi, how're you doing? I've recently purchased a R4DS and it works great. I was talking to a few lads who use the M3 Adapter (slot-2) and use GBM instead of MoonShell+DPG files. How do these methods compare in terms of quality and functionality. Can I even play GBM files (I'm assuming it is a filetype aswell as a movie player name.) using a Slot-1 device? I plan on converting about a dozen of my DVDs to work on my DS and I'd rather focus on the better format.
