After reading threads in this form, i saw that WinAvi should handles Batch files. So i downloaded the program and tried. When i converted the 3 movies, each one took around 5GB (and not all of them together).
Can i instruct WinAvi to encode them in a way they will fit 1 disk?
Sorry, I never used WinAVI. By the way, even TMPGenc works with batch files (see from the Save the first CD's project part of http://www.afterdawn.com/guides/archive/dvd2svcd_with_tmpgenc.cfm ).
But 8 hrs seems a bit too long; are you making VCD movies or not? I'm afraid VCD is to less for that AVI (which has a resolution similar to a DVD, even if their 'nominal' resolution seems too much for such small - 800 MB - movies) and more than VCD movie won't make all movie fit into a DVD).
You have to choose: a) reduce their resolution at least to SVCD (approx 1.6 GB per movie) and put many movies on a DVD (since the compresstion of a 720x576 movie into a 800 MB AVI will have already surely spoiled some quality) or b) keep them DVD-like and put one movie per DVD.
8 hrs is about right, for the settings in that guide.
It WILL retain the most quality you can expect from an AVI though.
You can cut the time down a LOT by changing the Motion Search Estimate, and choosing one pass CQ-VBR instead of 2 pass VBR.
