1)Don't bother upgrading. HBC 1.1.1+ are only for vWii compatibility. It provides no benifits for the normal Wii and even breaks a few things due to the title ID change.
2)You don't need DVDX. It's been superceeded (by HBC 1.0.7 and up).
3)Try using the FTP server in WiiXplorer.
Also, don't bump your posts unless it's been more than 24 hours. You know those rules you agreed to? Yeah, that's in there.
