Wii Encryption and DVD Dump

I have two questions.1) Is there any type of system patch out that stops the encryption of data when it's copied from a Wii to an SD card?
The copy process is slow because data must first be encrypted.2) I've dumped a Wii ISO using Waninkoko's DVDDump tool. Does anyone know whether they are decrypted as they dump (therefore they're ready to be burned when they finish dumping) or do I have to decrypt them post dump?

It just makes an ISO. It doesn't decrypt them. It assumes that you just need an image file of it and don't have an LG drive on your computer :)
