Haven't seen that option in Recode. If you need to compress it to fit on single layer use DVD Shrink. Go to file>open disc image. Or if not you can burn it w/ burning rom.
binkie7: Yeah, I normally use shrink when I have an ISO file but it seems that Recode is a bit faster so I was hoping there was a way to use Recode to do it. I had a feeling that was the answer though. Thanks.
