This would end the one headache I have with IMGburn: I have to manually copy a DVD over to my local drive before burning at full speed.
I have Gigabit ethernet--it can't be the network, because I pull 25MB/s and I can't even burn at 8MB/s (6x) off of the network. It can't be the USB, because it works fine from the HD to the USB burner. So the conclusion is to cache the files to the local HD before you burn. And yes, I would be okay with it being an option I would have to manually go in and check.
