I bought the verbatim DVD_R DL 3-pack. I have used one till now, and it has worked perfectly (DVD decrypter Write mode, 2.4X fixed write speed). I am keeping my fingers crossed; I will have to test more before I can say with confidence that this works. FYI, this media is actually made by Mitsubishi as per DVD Identifier.
Just want to give an update. DVD players that I have tried my DL discs in. Toshiba: Model SD-V392SUA Works Sony: Model DVP-S550D Works Samsung: Model DVD-V2000 Does Not Work Toshiba: Model SD-3900 Works
