The interesting thing about the PlayOnHD series 2 media-players is that they come standard with the new and very much improved GUI but also hardware wise harbor the latest Realtek 1185 chipset, and that changes a thing or two as the performance issues we had noticed in 1080P content playback (with very high bit-rate) are now a thing of the past.
That Realtek 1185 chipset has an increased clock frequency, 500 MHz coming from 400 MHz on the original version. And it makes all the difference.
