I have the best software for DVD backups imaginable and a very nice GO Video DVD\VCR player as well. Even with all that going for me, I cannot produce a DVD on my pc that will play in my home player.
The generation of the player, options included and cost all have bearing on whether a home player will accept a non commercial DVD.
You also have to choose the right optical media, usually CDRW and set your program up correctly as well.
Read, experiment, buy a newer dvd player.
