It doesn't look like your initial SetMTMode call specified the number of threads, try (5,0). You might even be able to get away with Mode 2.. There seems to be conflicting opinions about whether it works properly under any mode less than 5.
Is your input clip progressive? You shouldn't be resizing before a deinterlace also, and I don't know if trying to resize an interlaced clip would mess up MT either ?
You could also try resizing before your Dub operation ?
