Sometimes not always when I make a backup (movie only) it will not play on my stand-alone player. It will load and recognize the disc, but when I press play it goes back to the play menu and will advance no further. The strange thing is the same backup will play on both drives on my pc. If make the same backup full disc, it then plays fine on everything. Most backups I would rather have movie only to delete previews and for better quality. Eg: Starwars IV movie only plays fine on everything, Starwars V movie only won't play on my stand-alone player but will on my pc. Starwars V full disc plays fine on everything. Any suggestions? TIA.
