Re-Render?

I have rendered one project. If I make changes to the chapter selection menus do I have to completely render the project again? It takes so long to render a project. I have noticed that when you look at the screens in preview it looks totally different then the actual finished project. In preview my buttons looked like they fit the screen perfectly before I rendered and burned. When I look on my set top player, the buttons dont fit so I have to go back and make changes. Its silly that I can make a 1 minute change but then it takes another 8 hrs to render the whole project. The project that i am working on now is a 2 hr video. Should it take that long to render? And another question, what is a good video grabbing app to use? I use vegas to grab the video off my DVcam and it pulls files into a really huge .avi files. The project that I am working on now is about 30 gbs total in size. HELP!!!!!

If you feed an AVI file into DVDA, then yes, it can take a long time to render - and your only option at this point is to re-render when you re-prepare the project. DVDA must first compress the AVI information into a MPEG-2 video stream, then compress and multiplex the audio.

My suggestion would be to either:

1) Render to MPEG-2 using Vegas (the project prepare will still take place but it shouldn't take nearly as much time) - be sure to use the appropriate template when rendering in Vegas - you want to use one of the DVD Architect templaes (NTSC or PAL depending on where you are).
.
2) Use a short clip in place of your movie while you work out the issues with your menu. One you have a menu you like, replace the short clip with the actual movie.

As far as your button placement, it sounds like you are not taking into consideration the 2 safe areas. You should enable the grid for the title and viewing safe areas so that you can correctly position your buttons to fall within those areas (DVDA will give you a warning message if you have buttons outside of these areas).

DV data stored in an AVI file takes up about 13GB per hour of video/audio. There are some cards on the market that will let you capture as MPEG-2 which takes up far less space, but MPEG-2 is harder to edit with and you lose some quality since it will typically need to be re-rendered when you put it on a DVD.
