Installed Homebrew, Bootmii, and DVDx all at once, all worked successfully. Loaded all of the different MPlayers thru Homebrew Channel, none will play a DVD. USed another tutorial, it removed some ISOs and replaced them I believe, said it worked successfully. But when I use the MPlayer channel, the channel loads fine, but when I tell it to open the DVD, nothing happens, just sits there until I reboot. I've tried all of the Movie Palyers on the Homebrew Browser, basically the same happens to all of them. I noticed even after the ISO change, that when loading the DVDx app thru Homebrew channel, I still get the 2011 error relating to the DVD stub ticket.
DVD Video playing is a little hit and miss on Wii unfortunately. I've never been able to get it to work but haven't spent much time trying. Just a heads up for you really.
Not really doing much Wii stuff these days.
