anon125:12.1 - i cannot find a FIT TO DISK option is it "automatic quality" ?
Yes. That's the option you need. Sorry, but you must realize that Studio 12 is a 13 years old software. Memories are vanishing slowly.
anon125: also how does kbits/sec now at 8500 affect anything?
It's the bitrate = the amount of data used by the encoder to process 1 second of video. There can't be a higher bitrate for a DVD. Is it the value calculated by Studio with the Automatic quality setting ?
anon125:also there is no point making huge files that will be shrunk when on the disk - how do i make them smaller?
Why are you constantly talking about "making files" ? You are editing video clips in Studio, and I repeat, whatever their size, Studio will make a DVD with them.
