You're talking my language with Toast & a mac lol!
If you're burning a dvd you must choose UDF format. Which version of Toast do you have? For dvd's click on Data tab, then press the advanced button. Then choose DVD-ROM (UDF). ALso don't burn at max speed. Some set-top players are fussy for brand of dvd disk also. I use Verbatim mostly.
I've never tried burning an audio cd with CD-Text b/c I don't have a player that can recognise it (my stereo is many years old, lol) I don't know how to create CD-Text but, go to Toast's help & type in cd-text. Also go to their support site for more info.
