RV8 blurry frames

[NoX1911]

I'm trying to encode some RV8 videos for my s60 mobile phone with real producer 9. Strange thing is that some frames get blurred (like field interpolation) but all post processing filters are disabled. Its best visible if you encode branded videos. I tried all possible settings (sharp,...) but nothing helps. Only solution is to use RV9 but thats not supported by mobiles (i think). Is it the "nature" of RV8 format to produce such artefacts or is there any solution?

Example video:
Download (rar file) (http://de.geocities.com/heldimzelt1638/video.zip) 350kb
(german audio, just watch the branding, there is audio offset but doesnt matter atm...)

176x144
15fps
2-pass
128kbit max
75kbit avg
11kbit music

Avisynth script serving real producer:DirectShowSource("guckstdu.mpeg",25)
changefps(15)
bicubicresize(176,144)
brand=ImageReader("nox.bmp")
alpha=ImageReader("nox-mask.bmp")
Overlay(brand,x=147,y=20,mask=alpha,mode="blend",opacity=0.75)

Hard clip, no chroma informations, very low bitrate. RV8 cuts where it can.

Interesting, but I am afraid this is not a known problem. I looked at the video, and I can clearly see the blurry frames (mainly by the logos), but I do not know what causes them, or how to fix it.

Was this encoded with an older version of the RealProducer GUI, or the most recent cmd line tool (Producer Mercury Alpha w or w/o some 3rd party GUI)?

I tried similar settings with RealHandy 0.4 and the latest Producer. I can see the problem there as well, so there does not appear to be an easy fix. If I find some time, I may look into this some more to at least explain it, but no promises, and no ETA.
