Multiple AVI's onto 1 DVD

[Nuwanda]

I've looked around a bit and found a lot of informtion but i just have a couple of questions. Just something I wanted to clarify really before goin ahead with the encoding.
I have a couple of 700-800MB AVI's which i want to put on DVD. The way i plan to go about this is BeSweet/AC3 Machine and AC3 Fix for the audio and TMPGEnc for the video. The audio is fine, i got that part in my head but when it comes to video, almost all guides say 'just choose the media size and the bitrate will be set automaticall'. Now since i got 2 seperate vids i'm guessing this is not what i should be doing? How do i go about this - selecting the right bitrate?
Another thing is i've read the guide on how to make a really cool Menu, but how do i put it into the DVD? I havent gotten to the part of opening Nero etc so i havent seen it there as yet. Just a quick word on that would be nice.

One last thing..what format should i encode in? 16:9, 4:3 etc...how would i find this out (there's a way thro G-Spot i think, not sure how tho).

Thanks!

The bitrate you should use can be calculated using a bitrate calculator - https://www.videohelp.com/calc.htm or http://members.dodo.net.au/~jimmalenko/calc.htm can assist. Input the total running time of both movies combined, select the audio bitrate you will use and then use the figure in the Calculated bitrate field.

http://members.dodo.net.au/~jimmalenko/AVI2DVD.htm might have some useful information regarding bitrates, frame sizes and a whole heap of other related questions if you plan to use TMPGEnc Plus.

There are two main schools of thought regarding AVI to DVD conversion and aspect ratio. One says 4:3 under all circumstances becuase going to 16:9 requires a greater amount of vertical resizing to achieve, and all resizing is damaging to a degree. This is a valid argument up to a point, and if you only have a 4:3 TV then there is probably little to be gained.

The other school of though is that if the resolution is larger enough to begin with (say 620 x n or better), and especially if you TV is widescreen (or widescreen switchable), then 16:9 is valid. I generally do my widescreen conversions as 16:9 because I have a 16:9 switchable TV and the increase in playback quality is worth it.

But each to there own. It doesn't cost much to try one of each for yourself and see what works. That how I decided in the end.
