Very helpful, thanks. I'm a little disorganized right now. I have the Pioneer burner (DVR-105) that I've used for years and I have an LG 4167B that I have just sitting because Nero 5.5 doesn't like DL drives. So, this Sunday we have a local computer swapmeet and I'll look for Nero 6.6 or just buy 7.0 at Fry's and install just Burning Rom (that 7.0 is so bloated). Once that happens I'll go to town on those -R verbs and do some benchmarking. I did see the Nero scan thread and somewhere there, there is a link on how to interperet the PIE and PIF outputs. I'll take another look for it and post here for the enjoyment of all.
