Thanks for the explanation! Well I went to Norcent (my DVD player) and they don't even show they make DVD players (LOL). So I googled and got this: http://www.digitalfaq.com/media/dvdmedia.htm Seems my choice of Sony should take care of the problems on mine and play in everybody else's DVD players. Judith _______________________ Judith, A "set top" player sits on 'top' of the TV 'set'. Of course, this probably dates me a little since 'set top' was the term used to describe cable TV receiver boxes when they first can out (they were placed on top of the TV by the installer as a rule). ;O) In your case, the actual difference lies in supported DVD blanks. Every drive manufacturer has a list of disk blank models that they've tested and approved for use with their hardware. If you try using a brand not on that list, you stand the chance of using an incompatable disk (burns fail or the disk corrupts more easily than 'authorized' blanks). For the most part, the differences between various blank disk models are in the dyes used for the writing layer. In a nutshell, the more expensive the blanks, the better the dye layer (but don't ever adopt that as a steadfast rule cause sale prices often depend more on distributor volume buying than quality). Regardless, head over to your burner maker's web site and see if you can locate a list of 'tested and approved' blank models to choose from. I should also point out that it will still be possible (though very rare) for a disk approved for use in your burner to still have problems playing in a drive or player that has not approved that particular brand. There's not much you can do about that other than to switch to a blank brand that is approved for both players if that situation does ever rear its ugly head.
