I am new to DVD recording. In the user guide for the Pioneer 5100H I read about the "Disc Back-up" function. It states it can (a.o.?) perform a full (backup) copy, using the HDD as temporary storage, to either a DVD-R or DVD-RW. The process seems very easy indeed. I have also enabled 'Optimized recording' - kinda like 'fit to space'. Now I have 2 questions, before I try and mess up some discs: - Will I be able to copy a >4.7 GB disc this way ? (using optimized rec). - Will I be able to backup/copy my non-region coded, non-protected 'factory made' DVD-Video discs this way ? (it concerns factory made product demo discs - I know if it is CSS scrambled it won't work). If it does work, will it copy all contents, menu's included ? Also the Sony BIT enhanced-DVD's (non protected?) - would it for those too ?
