Hey I'm not complaining, like I said before, I love the results DVD2one gives me with movies 6 gigs or smaller, but once you get past 7 gigs, yes the pulsating effect is very noticeable on many movies. I'm not a perfectionist, just don't want to see the picture shifting from left to right for 2 hrs. Hopefully this flaw will be corrected with the next version of the DVD2one engine. I don't know about the rest of you, but to me, even artifacts aren't as annoying as the pulsating effect. And my playback devices are the HP DVD writer in my PC, my DVR104 also in my PC, my Philips DVDr985 DVD recorder, and my Sony 301 DVD Jukebox, all pretty much state of the art. May I suggest to those who don't notice the pulsating effect on movies greater than 7 gigs, you may not have a newer monitor, which will show more detail...Sometimes it's better to own older products because they won't show the many flaws that are inherent in movies. This doesn't only apply to movies copied with DVD2one, but many older movies were mastered poorly on the original DVD, and older monitors won't show the problem nearly as badly as newer monitors will.
