I hope this is where this belongs. I am not really new to burning dvd's, I have been doing it for a bit, I don't understand all of the technical aspects, but i can get by. I use a variety of programs including Nero and Dvd santa, most times i get pretty good results. I recently burned an avi using nero, the majority of the dvd was very good, a little more than half way through, the dvd got very jumpy, moving a frame a time, and those frames were distorted. I then took that avi and used dvd santa to burn it, again the majority of the dvd was good, except the same thing happened again at a different point on the dvd. I was reading a little about ffdshow and was wondering does that take the of xvid or divx as a converter? would it help to DL that and uninstall the other two? Does Nero and santa use their own codex to convert avi to burn to dvd or do they rely on what is on the machine, and if they do, could i plug ffdshow or a different codex into those programs?
