I just bought Toast 8 and am a complete novice. I bought it to burn avi video files onto DVD discs for viewing on my TV using a standard DVD player. I have no idea what all the various video file formats mean (avi, divx, mpg, mov, etc.) or when and if I need to convert from one to the other (I wouldn't mind finding out more about this if anyone can direct me to an appropriate place to find out more about all these video formats). However, my question is with regard to a video_ts folder (yet another format?) which I tried to burn onto a DVD-R disc (standard 4.7 GB) using Toast. After I dragged the folder onto the Toast window, I got the message that the disc did not have enough space for the file. So I then tried my old Popcorn 2 and voila, no problem - I have the video on disc. Popcorn does indicate that it does auto-compressing which I assume means that it shrinks the file to fit onto the disc. So what am I doing wrong with the more high-powered program, Toast Titanium 8 since it is not burning the folder onto the disc? I'm using an intel iMac with OS 10.4.11.
