Catalina is biting me again, or should I say the newest OS is causing issues. Everything worked great prior to Catalina, and now that I downloaded it, nothing is working as it did. Purchased and upgraded to Toast 18. All I want to do is download my own self made videos and compile it on a DVD. When I do so, the files come out with "Null" on them and they will not play...what am I doing wrong. Very frustrating.
