Rename the file. Avisynth support of Japanese, Russian and various special characters is close to non-existant.
Also remove deen, there is no point in using 1080p raws if you destroy all the detail like that. Chuu-bra!! is just upscaled, btw... I think it's 720 at most, so you should spline36resize(1280,720) in your script.
No need to fielddeinterlace either. The BD was very likely progressive, but in the off-chance it wasn't, it was already IVTC'd by the raw providers or whoever for them, so adding fielddeinterlace will only worsen the quality.
Also, since it's progressive, you shouldn't put interlaced=true in your converttorgb32. I would personally discourage the colorspace conversion, though. I assume you're going to make lossless clips, so you should make them in yv12 to save space.
Last but not least, quit using virtualdubmod. Use the latest virtualdub
