If burning data to DVD+R (i.e. using a combo burner such as Lacie's based on the Pioneer A106) and using Toast DO NOT use the drop down option "DVD". This function will work fine with DVD-R's but with DVD+R will create a DVD that is unreadable by OSX (though the data is fine and was actually verified within Toast).
Set Toast to Data CD and change the format to Mac OS Extended CD (to allow a 4+gig CD to be created.) It would have been helpful if this warning had been notated ANYWHRE by ANY of the companies producing such products.
I am still unable to read any DVD+R back ups I made with this DVD function on any Mac, if anybody has any information I would appreciate it. Of course Apple drives are intentionally crippled to not read DVD+R but an external drive is only hampered by the OS itself. It may have something to do with UDF formatting (so much for "Universal"). As far as I know Panther retains this inability despite the rumours otherwise. Apparently the UDF reader by SAI does not work with 10.2.8 or 10.3.
