Apologise if this has already been answered in a previous post. I have a DVR-109 with firmware 1.40. I can very happily burn CD-R/RW, and DVD-R/+Rs, but I’m having problems when trying to burn DVD+R DLs. I’ve used two programs (DVD Decrypter and Nero) and tried two makes of discs (Memorex and Verbatim) but I always receive an error, In DVD Decrypter I receive and I/O Error and with Nero I receive an ‘Unable to start burning disc-at-once’. Has anyone encountered this? Any suggestions, even “you wanna replace your drive mate”, would be most appreciated.
