sorry for not answering your pm but i had alot todo lately i just finished a "Detail Preservation side by side compare" of RV9 vs Mpeg4 (XviD pre 1.0). I used the following audience file for it and changed max-bframes in the second pass to 1 in the stats file maybe you have some ideas how this can be further improved, but i think the inloop filtering makes it impossible. I also post the PSNR results their are not far away from eacht other and the XviD one with PP immitates alot the look of the inloop RV9 filtering btw,

Code:
<audience xmlns="http://ns.real.com/tools/audience.2.0">
<avgBitrate type="uint">508000</avgBitrate>
<maxBitrate type="uint">2200000</maxBitrate>
<streams>
<stream xsi:type="videoStream">
<pluginName type="string">rn-videocodec-realvideo</pluginName>
<codecName type="string">rv9</codecName>
<codecProperties type="bag">
<encoderComplexity type="uint">80</encoderComplexity>
<customPacketSize type="uint">16000</customPacketSize>
<noisyEdgeFilter type="bool">false</noisyEdgeFilter>
<calcPSNR type="bool">true</calcPSNR>
<secondPassFile type="string">MyAnalysisFile.rva</secondPassFile>
<!-- Pattern Adaptivity Only if used -->
<!-- Scaling Factor Only if used -->
</codecProperties>
<encodingType type="string">vbrBitrate</encodingType>
<quality type="uint">100</quality>
<maxStartupLatency type="double">60</maxStartupLatency>
<maxFrameRate type="double">25</maxFrameRate>
<maxKeyFrameInterval type="double">10</maxKeyFrameInterval>
<enableLossProtection type="bool">false</enableLossProtection>
</stream>
<stream xsi:type="audiostream">
<pluginName type="string">rn-audiocodec-realaudio</pluginName>
<codecName type="string">cook</codecName>
<codecFlavor type="uint">28</codecFlavor>
<streamContext type="bag">
<presentationType type="string">audio-video</presentationType>
<audioMode type="string">music</audioMode>
</streamContext>
</stream>
</streams>
</audience>
