I wasn't aware that applied to the 7240s. The few times I've seen DVDRam mentioned with this drive it seemed fine, like the review here at MyCE.
Hard for me to recommend LG since I don't keep up with the dvd burners from them very well. When did they last release a dvd drive anyway? They've come out with a blu ray burner fairly recently. Edit: Dang, even that was over a year ago.
Maybe I should do some more reading and less talking!
