Hi: I have an Emprex 16X DVD Player/Recorder that handles +r and -r DVDs. Using W2K and CloneDVD2 and AnyDVD to make copies. Is it possible to put a +R disk in the machine, clone it to a hard disk file, then replace the DVD with an -R disk and record it or visa versa. I've always used the machine on -R disks (cloning) and have no problems - Have never went from -R -> +R or +R -> -R. Thank you in advance for responding.
