I don't know what the best supported format is to input to Riva FLV Encoder for youtube/myspace FLV output, but I tried using WMV.
In Vegas saved as WMV using the following settings:
Format: Windows Media Audio 9.1
Attributes: 128kps, 44kHz, stereo (A/V) CBR
Mode: CBR (2-Pass)
Format: Windows Media Video 9
Image Size: 320x240
Pixel Aspect Ratio: Square
Frame Rate: 23.976 (The video is a film)
Seconds Per Keyframe: 3
Video Smoothness: 100 (Sharpest)
Internet/Lan: 1.5 M
*Under Project Settings, I set the Deinterlace Method to None since the Riva Encoder would deinterlace for me anyway.
Riva doesn't accepted WMV 9, so I tried using WMV 8 by changing the mode under Video to WMV V8 expecting same quality results. Instead I get a smaller video file with a lot less quality. Using WMV 9 I got a 30 MB file, but with WMV 8 I got a 12 MB file. I don't get how this is happening with the same settings unless it's just the WMV 8 codec. If that's the case, what other format supported by Riva would be the best to output as a FLV file for youtube/myspace?
Video Codecs Supported By Riva FLV Encoder:
Cinepak Codec by Radius, Cinepak by Supermac
Intel Indeo(R) Video R3.2
Microsoft Video 1
DivX 3 Lower Motion, DivX 4, DivX 5
TechSmith Screen Capture Codec (TSCC)
MPEG-4 (XviD, MP4, 3GPP)
Sorenson Video 3 Pro with the audio codec MP3, IMA 4:1 (nicht QDesign Standard und Qualcomm PureVoice) or wihtout audio

Not supported: QDM2 Audio Codec
Windows Media Video

Not supported: WMV 9
I hear Flash is supposedly the best format you can use when uploading to youtube, WMV being second best.

You will only get a smaller file if the bitrate is lower. You haven't specified a video bitrate in your settings (above).
If Riva will take an avi file, then you could output from Vegas as an uncompressed avi file, then encode with Riva. That way you don't compress it multiple times.

Ok, so the audio is fine now. It seems that the problem was the bit depth. On Vegas, it is set to 24 by default and I guess Riva has trouble encoding 24bit audio. I just needed to change it to 16bit for it to work.
However, now there's another problem. When rendering to uncompressed AVI the file splits after 4GB. I can't figure out a way in Vegas to set it so it saves the video as one big file.
