[QUOTE=jimmyweez;2050356]Thanks for your quick response! I am using Nero 7 Ultra edition in conjunction with DVD43. I have tried basically every kind of way to change the booktype, but none will work. I have also tried using different buring programs including dvdclone and 1clickdvdcopy pro. They all work fine on my computer, but won’t play on the standalones I try them on. Thus I assume it is a player problem, not a burner (although please correct me if I’m wrong). that’s why I’m looking for a standalone player that will play the DVD+R DL format without a changed booktype. Any suggestions?[/QUOTE]
Have you check to see if there is a firmware update for your burner and also contact Sony support for your drive as to what software would set the booktype to DVD-ROM at the time of the burn? I do know Nero does set booktype to DVD-ROM capability drive. I had a old liteon drive but with the liteon utility each time I wanted to burn to DVD-ROM booktype- I just had to set the feature on cause it didn’t allow the DVD-ROM setting to be saved. But first would be to contact Sony tech support for your drive.
