There is a one touch record button. With one push it starts recording from what input you have selected, to the HDD, or a DVD, whichever mode you have it in. One push starts recording, but more pushes make it a timed recording, at 30min. per push.
There is a one touch copy button, which does a fast copy of whatever HDD recording you have highlighted, to a DVD. I don't know if it will do a highspeed copy from a DVD to the HDD, because I haven't tried that yet, but you can do a HS DVD-to-HDD copy, so I assume so.
Back to the DL disc question... I had intended to pose the question, "Has anyone recorded a highspeed copy, video mode, from HDD to a +R DL disc?," before I saw someone else already had brought up the subject. I just picked up some Maxell +R DL discs at Sam's, 30 for $60, and want to try it. The manual definitely says it is possible to record to a DL disc, high speed from the HDD. But, in one place, the specs in back, it indicates that +R discs can only be used in the VR mode. I find that hard to believe. I don't have the manual with me, but as I recall, it does say that in some circumstances, it will not recognize a DL disc as having the second layer. I think that applies to the "Optimize" function, as well as reading in HS. Well, I guess I'll just have to try it myself, as soon as there is something longer than two hours that I want to put on disc. If anyone else tries it, please let us know!
