I have a samsung drive (according to the comparison chart online: 2 wholes in the tray) [bold]Wont play:[/bold] dvd-r = dvd-iso data discs dvd-rw = dvd-iso data discs dvd+r = dvd-iso data discs/dvd-video (Straight copy from an actual movie) Mediums used for above: TDK, Fuji, Verbatim [bold]Will Play:[/bold] dvd-r = dvd-video (Straight copy from an actual movie) dvd+rw = dvd-iso data disc / dvd-video (Straight copy from an actual movie) So basically, the type of drive I'm looking for in the following priority: [bold]Primary formats I need:[/bold] dvd+r dvd+rw [bold]Secondary[/bold] dvd-r dvd-rw 3rd: cd-r cd-rw According to my understanding of why DVD-R only worked because of the DVD-video format. I figured the same theory would work for DVD+R, if it was a straight burn from a movie, but that's not the case. People keep listing the drive S 616T to be the superior must have, that plays all formats. When I see a listing in ebay it doesnt include +R or +RW anywhere. So which Samsung drive do I have? the 616 or the 605? and which drive (based on the priority lists above) will I need to replace my current drive? I do realize there's a hit and miss with formats, but based on the mediums I've tried, I realize my drive completely rules out the formats I need. Please help.
