Hi Shannon! Welcome to the forum. Some standalone players prefer either +r or -r dvd's, and the quality of the media you are using can have an effect on the playability of the disk. The software you use, copy protection, can all be a factor. Is the dvd in question, a movie? Your DVD player appears to support a wide range of media, so I would suggest you try different software. I use DVDSHRINK and DVDCRYPTER to backup all my movies. Others use ANYDVD with CLONEDVD, and a wide variety of other solutions.
