i want the quality good, but the file small. i tried tons of different settings and the file is huge, the quality sucks, and it takes 40 minutes, at the minimum, to render. please help me out.
You don't get both. Good or small, take your pick. If you want it small, Windows Media 9 is your best choice, but you'll lose quality. What is the final delivery to? If it's to DV, then you need to stay DV, and render to the NTSC DV settings.
if it's to the web, then Windows Media is the best solution for files streaming at less than 1Meg.
If it's to DVD, then MPEG 2 is your only choice.
If it's to VCD, then MPEG 1 is your only choice.
If it's to SVCD, then you have a lot of choices including avi.
But, avi is the typical standard for delivery/archiving, unless you'll never be going to tape again. then MPEG 2 is the standard, and anything faster than 8Mbps is a waste of time, because most players can't play it.
Does any of this help?

Please tell us
what format your source video clips are (DV, MPEG, whatever)
What are you doing to the video in Vegas (a lot of FX or just cuts-only)
what format exactly are you trying to render them to that you say is too big and the quality is too low (MPEG, DV AVI, Uncompressed AVI, WMV, RM, QT).
