A WAD is a general term for a type of file that can be installed into your NAND. WADs can be several types of installs, system menu, IOS, applications, and forwarders.
A channel is anything that puts an icon in your system menu to select from (ie the aformentioned "applications and forwarders"). A forwarder is a specific type of WAD that just looks for an app and launches it instead of actually including the app inside the wad. So if you determined that your wad installed a channel and that depends on files being on your SD card, then that's exactly what it is, a forwarder channel.

Ok if i go down the route of it being a forwarder, how do i get it to look at the USBHD instead of the SD card
See my earlier post:
In my experience it looks at sd first, the usb. So if i want it to load off of the USB I move it to my usb and make sure it is not available on my SD card. This should cover your for the USB loaders using the channel installed by the guide. If you are using other forwarder wads, there is no guarantee it is programmed to look at the USB device.
