I'm sure you can write 16x. That's still extremely slow compared to the bandwidth of your ata bus. Normally the 80 wire cable comes with the drive. Shouldn't be a problem. Almost all DVD writers and players can READ dual layer DVDs going way back. That's what motion picture DVDs are. Yes dual layer DVDs should be playable in standard home DVD players. But check the data base to be sure your player is dual layer written compatible. <http://www.dvddemystified.com/dvdfaq.html> <http://www.videohelp.com/> Why didn't you share your question with the group? I am trying to help everyone not just you. I think it was selfish of you to not put that question to me on the group list. I am upset you felt your question was not list worthy thus depriving the group of vital information they may have an interest in without having to ask me later again. Do you not understand that these lists are full of questions that most are thinking but not asking? k On May 28, 2005, at 2:01 PM, Wayne Clodfelter wrote: > Hi Kunga, > > Saw your post re Pioneer 109s, I have a couple questions you may be > able to answer, if you don't mind. > > Are dual layer discs playable in standard home DVD players, or do > they have to list dual layer in their repertoire? > > I have a Sawtooth G4 and I suspect I may not achieve 16x write > speed in this unit due to system or IDE bus limitations.
