DVDs Mpeg-2 - is 720x480 60i the best you can get starting with 1080 60p?

I have tried various renderings starting off with 1080 /60p footage - all of the approaches issued warnings of compression - until now.

I just managed to do a rendering by picking MPEG-2 720x40 60i and this required that I separately render the audio to generate an AC-3 file at 48,000 Hz, 192 kps.

I then loaded up DVD Architect Pro 6.0, picked the two files and proceeded with the burn.

Is this a good protocol or is there some combination of approaches that will give me an end result of 1080 on the DVD as opposed to 720?

I must say that on my PC I don't find that the 720 DVD quality is any less than that of playing the 1080 .mpg file running in Windows Media Player.
 
DVD is a standard-def format. You can't put HD on a DVD; you have to downrez it to SD. For an NTSC user that means 720x480, and that can either be at 60i or 24p. That's all a DVD can handle.
 
If you want 720 or 1080 .mpg it will have to be burned to Blu-ray. Here are the accepted formats.

You did it correctly. This is what the DVD Architect NTSC Widescreen template under MPEG-2 is for.

You really do want to do this from Vegas instead of having DVD Architect recompress it.

Thank you for the information.

"You really do want to do this from Vegas instead of having DVD Architect recompress it."

I see a Burn option under "Tools" in Vegas 12. Will try that. Will see if I can see a difference compared to rendering in Vegas and then burning from DV Architect, where, it seems I have been doing two compressions.
