That's the truth about recordable DVD media. There are some players that will never play anything but factory media.
You can improve the odds with having DVD+R and DVD-R media on hand and using simple software like DVD FLICK but what you ask is not possible today with recordable media.
I have tried creating DVD's with various programs, even tried a Magnavox VCR/DVD player-recorder machine; they played back on a computer but none of them played back on most of the DVD players I used. Magnavox said it would,but when I called them, they admitted that sometimes it doesn't work. Is there a program I can use that would work and doesn't cost a small fortune? Thank you. Bob H.
