Good day to everyone. I tried doing a search for the subject but was unsuccessful. If this topic has come up before please forgive me, I did try the search. As the subject says, I can burn a DVD on my computer, and it plays well on the computer. But for some reason, it won't play on my Panasonic player. I use something of a no-name brand DVD (blank, no label on face) and DVDBackup 1.3 as well as DVD2onX (this allows a copy to fit on a single DVD). All this is done on a Macintosh G5 Dual 1.8Mhz. None of the backups I made play on the Panasonic (model D23, I think) with the exception of a kid's school video I made using iDVD on the Mac, this one alone plays. The Panasonic also refuses to play all my MP3 cd's of varied brands (Sony, TDK, etc.) What seems to be the problem here? Is there an issue with the software I used to make the backup? I didn't use this software to make the kid school video. Can anyone suggest a solution or software to use on the Mac?
