For 640x480 videos, I like using 480x352. It cuts the file size without having noticeable quality issues at fullscreen. Basically, I like the tips in the old avtech guide - back when people were lucky if they had internet access at all, let alone highspeed.
If I'm aiming for high quality and compatibility, I'll use 640x480, but only if it's mpg and hosted elsewhere. With xvid, lowering the resolution a little doesn't hurt the quality at all, so there's no benefit to bloating the file size.
I'm on broadband now, with a direct server, so I don't mind putting a huge mpg version online for the fast downloads. I just won't do it on the local server where half the donators are on dial-up.

For DivX/XviD encodes I'd never exceed a width of 768. So 16:9 would become 768x432 (it's proper 16:9, and width and height are multiples of 16). The reason for this it that I have playback issues with wider vids. The right side of the vids which exceeds the 768px border is shown as color noise. It happens with different players. I'm sure if it happens to me, it'll happen to others too. With WMV encoded vids I don't have that problems, but unfortunatly the most WMV encodes have bad quality.
For 4:3 I'd go meanwhile to 640x480. The gain of compressibility isn't proportional to the loss of resolution. While a 320x240 vid has only 1/4 of the resolution of a 640x480 vid, you can be happy if you can reduce the filesize to 1/2.

I like 640x480/360 and 512x384/288 for sources that don't come fully scaled (ie End of Evangelion and Voices of a Distant Star) but I can bear going down to 480x352. Anything below that can look decent, but not exactly right.
Sometimes however, as I've learned lately, you really don't have a choice but to reduce your framesize. Some sources are so incredibly hard to compress no matter how much filtering you do.
