Here's one for the download record book.
Just now, and it did it two times, the X10 was doing the Sony covert download (at 6Mbps) and I started to download a movie trailer which it started at about 11Mbps. As the trailer got to 90%, I went back to settings and watched the download speed, curious to see if it dropped back to the single digits as the trailer d/l ended and the Sony covert started again.
Well for one instant sample, it read 58.1Mbps, which is exactly what my PC gets when wired to the same router.
I did it again for another trailer, and it repeated the identical process, jumping to 57.6Mbps as one function ended and the covert download started again.
This would lead me to believe that there is some sort of clamp on this whole 4K SEN thing, and that for one moment in time, the Japan Clamper doesn't catch it immediately.
