My bad, i've misunderstood what you wrote. One test you can make in that case is to extract the sup also with eac3to for exemple, and compare the TSMuxer result with the sup extracted with SE. But indeed, a sup extracted and remuxed on a video with the same size it's extracted from should produce the same result.
Or maybe... i don't know exactly what is "DVB-SUP", so maybe my assumption is wrong... Is it a way to call a .sup extracted from a Blu-Ray ?
