My frit question is how many extensions to the ISO CD-ROM format are there .... And what is the differnce between ISO mode 1, mode 2 and mode 2 with the two forms ... Mode 2 form XA 1 and Mode 2 form XA 2. I think it has something to do with Useable data per Block. But I don't know what that is which all in all results in Capacity in MB. But how much does a CD block useally hold whith no format associated with it. And what the problem with mixing modes it said some where you can put mode 1 with mode 2. I goig to end it here case I starting to get a little confused my self. So just tell me if you don't understand all of this and I'll try to refomat it.
