This is correct. The Finder doesn't support burning multi-session CD's, but Toast handles it just fine (though you will not be able to do so if you click Burn Disc... you have to click Burn Session).naodx said:I can't remember this for sure (don't work with dvd-rw's that much), so maybe somebody else will be able to answer this for you better, but I don't think that apple's built-in burning software will allow you to do multiple burns on a dvd-rw. If I remember correctly, Roxio's Toast allows you to do multiple burns, but again I can't remember for sure. If you want to replace whatever is on the -rw disk, you must erase it first (quick erase works just fine).
