How much of a difference does it make if I do not use architect to burn it?
You said that you have vegas pro 10, so you should have DVD architect as well and why not using it. But if you want to use another authoring software to create your menu and burn yr DVD, it’s up to you.
It seems that you want to play your video on computer AND dvd player.
1- playing on computer: You can render in most format, up to you, either wmv, avi, mpg, mov, avc, etc…
2- Playing on DVD player: you have only 1 choice. Render using mainconcept-MPEG2 NTSC DVD architect template for the video, and AC3 file for the audio.
But what’s the resolution of your original footage?
