Reducing the scenecut parameter will not solve this problem; it may make it invisible, though…

I reduced the scenecut parameter from standard 40 to 20 and now I do not have this type of error anymore

I strongly believe it depends on the material. With an iPod Touch 3.1.3 16GB I get artifacts with 3 refs and this movie (320×240, but lots of movement and panning):

Same with 2 refs is ok:

But I sure would like whether the latter works on iPod Classic.

I have gotten up to 11 reference frames with mixed references to work on my iPod Touch 3G 8GB. Basically, its a second generation iPod with the newer software. But, my old 3G Nano can only handle 2 reference frames.
