I've tried several blu-ray system and most only support Android miracast. The Sony system I picked up specifically says they support both Windows and Android. I've not had problems with the screen mirroring at all. It is just the surface pro 2 that seems to behave badly.
It works well for me, I believe the issue with the Home Entertainment Systems is that when they included Miracast Support, their developers did the old "hard coded connection string" looking for specific Android Devices (typically called out on their Support Site). Even the PTV3000 needed a Firmware Update to work with Windows 8.x.
Thanks for the compliment
For my setup everything is stock. It has only microsoft supplied windows and hardware updates through windows update. I've not installed any other drivers.
Now that's strange. Since the SP2 only has a single radio, wouldn't it need to connect to both the router and the peer-to-peer Miracast (Wi-Fi Direct) on the same band? So if the Sony Miracast only supports 2.4GHz, shouldn't the SP2 also connect to the router via 2.4GHz?I ran some additional tests, and the router is set to 5GHz (something like channel 149), while the miracast device from Sony seems to only opera at 2.4GHz (channel 6). There are no neighbouring networks operating at or at adjacent channels. Signal strength is strong for both networks.
Some tests today showed that connecting my internet wifi to 2.4Ghz (at a different channel than the miracast) resulted in no internet connectivity at all. Running at 5Ghz would allow for internet connection most of the time.
That maybe true, however when I had the SP2 connected to my routers 2.4GHz band, and to the miracast connection at 2.4GHz, the internet was never usable. If I connected to the 5GHz network for internet it would sometimes work for a while. With any extended time, the internet would stop working.
They mention Intel WiDi but it should also apply to Miracast since both are based on Wi-Fi Direct.Check the WiFi Access Point Frequency [p. 41]
Intel WiDi functions at either 2.4 GHz or 5 GHz on both the WLAN connection to the wireless router and the PAN connection to the Push2TV adapter. The operating mode of the PAN connection depends on the WLAN connection to the wireless router. If the WLAN is connected at 2.4 GHz, PAN operates at 2.4 GHz; If the WLAN is connected at 5 GHz, PAN operates at 5 GHz.
If you change your WLAN connection, the PAN connection might be interrupted

The Roku only has one radio. If it had to keep retuning the radio to different channels to stream and to hear the remote, performance would be abysmal.
Not sure why the Sony player is behaving that way.
According to the PDF manual for the Netgear Push2TV PTV3000:

The same thing occurs with the Roku 3 streaming box. Its remote control connection uses Wi-Fi Direct (instead of Bluetooth/RF/IR), and it will always follow the frequency band and channel used to connect the Roku box to the wireless router. Their dev said:
