I haven't used it but the converter must have some downloading capability since you have used it for that .
You can save the converted file to any folder you want it in.
What I tried was to see if I could just download & burn since that is what I thought you were doing. What happened it had me select Windows built in burner. I have rarely used it so I haven't tested it enough to say how good or bad it is.
I don't even know if my standalone DVD players will play the DVD with an .avi file burned to it. I suspect my LG will & my Magnavox's won't.
I chose .avi because it was first .
Most likely what you or I really need to do is use AVStoDVD or DVDFlick to convert any file format we choose to a DVD compliant folder & file set. You know an AUDIO_TS empty folder & a VIDEO_TS with .ifo .bup & .vob files in it. Then burn that to a DVD.
I didn't see it as a choice but I suspect a .mpg or .mpeg would be the second best choice for standalon DVD player compatability.
The better quality the download file usually the better the conversion to DVD compliant format. So I would probably go with 1080 & one of the programs above can reduce it .
If a .mpg file & a .mp4 might qualify then 720 because a DVD player rejects the larger size. or that's my understanding.
