I'm new to converting DVD into Divx and I'm a little confused as to which resolution to use when resizing in VirtualDub. The guide found one this site talks about a resize value of 640x360(352 when cropping) for 16:9 movies, but most of the films I've downloaded so far has different resolutions. 576x388, 640x272, and 608x336 are among the different resolutions that I've found so far. Almost all of my DVD's seems to be 16:9. The guide also talks about using a 640x512 setting for 4:3 movies, but when I did this I ended up with a Divx with wide black stripes on both sides. The output monitor in VirtualDub was also quite bigger than the input monitor. Hope someone can explain this to me.
