i recently purchased a psck of infiniti dvd rws to discover that they werent really rws at all. nor were they made by infiniti. i burned some data onto one of these so called dvd rws just to test it out but when i came to write over it i couldnt as it was only detected as a dvd r. i then took a closer look at the middle of the disc to discover the words phillips dvd-r written several times. thats write they werent infiniti DVD R/Ws they were Phillips DVD-Rs so if your concidering buying any infiniti discs check for writing in the middle of the disc to make sure they are what they say they are
