I'm burning with a SuperDrive on my 867MHz Quicksilver. I just got a pack of LiquidVideo DVD-Rs. When I burn the disc as DVD-ROM(UDF) with Toast the disc will play fine on my Macs but not the DVD Player on the TV or on my PC. The Mac recognizes the disc as a DVD. Are the LiquidVideo DVD-Rs the problem? I'm using DVD Backup, DVD2oneX, and Toast 6 to make my DVDs.
