avi to DVD, advice on settings

[zbgump]

I'm getting ready to attempt to convert an Xvid avi to DVD. I've never authored a DVD before and my computer is pretty old, so I'm hoping to only have to do it once. I would appreciate advice on getting the settings correct.

My source movie is 640x272 25fps, ac3 audio 48000 Hz 192 kbs.

I need to convert to NTSC. So I believe I should:

Encode with mpeg2enc, set size to DVD, frame rate ntsc film, enable 3:2 pulldown, set audio to encode passthrough.

Sound good? Also, does it matter if decode with Quicktime or mplayer? Should I check Letterbox?

Much thanks for any and all advice!

Make sure your movie plays with sound in Quicktime Player. You may need to install the ac3 codec from http://www.insaneness.com/ac3.html

Enable "Decode with Quicktime", don't use Passhtrough, enable Letterbox.

Thanks for the reply major.

I thought I should use passthrough because the audio is already ac3, isn that OK for a DVD? Should I reencdoe it as ac3 with a different bitrate or Hz? Or should I encode the audio as mp2?

Thanks again.

Passthrough is currently only for AVI output. You should simply use the preset settings for audio encoding.

Just a followup; I had actually already encoded my video prior to your first reply. I had the audio set to passthtough, and it seemed to work fine. It has played fine in two separate DVD players. Maybe I got lucky.

Anyway, thanks for the replies.
