1) Good news: if you use avs2yuv with -raw and then RawSource(filename, width, height, "YV12") it works already. When using "I420" U/V are permuted - I'm sorry I confused I420 and YV12.

2) Using the native format will be a little more work, as the frame positions are theoretically not equally spaced (the FRAME header can be different). But if I assume that there is no data in the frame header it makes it much easier. This will be always the case if the stream is not "interlaced mixed" - which AviSynth can't handle AND if there are no "metadata" of variable length.
