When I try to write .vob/.ifo files with CloneDVD 2 to a blank DVD+R DL, it doesn't recognize that the blank DVD is in the drive. I'm using Memorex DVD+R DL, and my dvd writer is a PBDS DVD+-RW DS-8W1P ATA Device with it's latest driver update. I'm using windows vista and

Does your drive support DL discs

Use Verbatim +R DL and booktype it -ROM.

yeah cause I've burned homemade DVD's using Memorex DVD+R DL discs with Windows DVD Maker.

Can I change the booktype with DVD Decrypter, then use it in CloneDVD? or does the change on work when you write a file with DVD Decrypter?

So what is the file your trying to burn to the dvd??? Is your computer a laptop?? Have you check to see if the firmware is updated? What does the exact error say in vista???

its the .vob/.ifo files of the DVD the Boondocks. My computer is a dell inspiron 1520 laptop, I searched google and didn't find any updates, also i went into the device manager to see if any drivers were available for update and it said there weren't. theres no error in vista, but cloneDVD simply doesn't recognize my Memorex DVD+R DL, I'm going to try using Verbatim's DVD+R DL, CloneDVD works fine with Memorex DVD-R, but not DL's.

Get rid of the memorex junk and only use Verbatim +R DL. Download ImgBurn and check out this guide.

ImgBurn is DVD Decypter without all the decrypting components. Freeware too!

It's not CloneDVD but the media you are using which are causing the problems.

Make sure you burn at a slow speed like 2.4x or 4x.
