I think you are confusing a DL-capable burner, and a dvd player that can read DL disks. Almost all commercial movie DVDs are DL/DS and it would be a rare DVD drive that could not read any commercial DVDs. I think the OP was burning on a DL capable Mac but could not read on the Dell. regards, sb On Sep 27, 2009, at 10:22 PM, Ronald Steinke wrote: > On Sep 27, 2009, at 3:21 PM, Robert & Susan Lloyd wrote: > >> I'm quite sure that the DVD player on my Dell should play them. > > Being "quite sure" is not the same as being right.
