sort of. iDVD can have up to 90 minutes of video on a disc. with DVDSP, it depends on the compression rate and the type of burner you use. DVDSP can create projects that go on single sided, single layer discs, up to double sided, double layer discs. the superdrive will only burn the 4.7gb discs[single side, single layer]. different media and burners are needed for anything beyond single side single layer discs. how much you fit on a 4.7gb disc using DVDSP depends on how compressed your files are.
