I've just purchased it, so I think it should be a new revision.

I don't understand why it chooses OV511 decompression despite it's an OV518+?
Why doesn't is use the OV518 decompression (included in Oleg's firmware)?

Image is totally unrecognizable "undecoded noise" . I assume it's caused by choosing wrong decompression routine.

Any idea?
