some DRM protected stuff such as SKY GO won't allow you to cast via Chromecast - but using a wireless display gets round the problem so again well done Ms.
Chromecast is still though an excellent device -- does a HUGE lot more than just run Google's apps -- I use it regularly for streaming local Video from a NAS server to remote TV's.
Limitation of chromecast though --1080 X 1920 HD is max you can Cast -- so all of you with those huge TV's and 4K movies -- until Chromecast gets an upgrade or a firmware change -- you are stuck.
@ Steve C - jerky video is often caused by SLOW I/O -- that's where RAID 0 comes into play - if you make an array of say 2 physical volumes into 1 logical volume (use RAID 0 so you don't lose too much data space from the volumes) then your I/O speed in therory could be 2X as fast as the single volume. Won't get that in practice but you'll certainly get significant improvement.
I'd suggest also getting a Chomecast device (in UK even with wallet sapping 20% VAT -- was that an EU tax abomination !!) around 25 GBP and even better if you get the Chromecast LAN==>wifi adapter -- here in ISL costs another 17 EUR (inc sales tax).

I'd suggest anyone who has one of these devices the LAN adapter is a "Must have" accessory -- plug into a LAN port in your cable box / router.
Unless you want to cast 4K movies this should work absolutely 100% -- even on a relatively slow Wifi connection. - Unless you have REALLY SLOW internet the lag is often caused by transcoding the video on the fly where slow I/O is a real bugbear. Using RAID 0 helps no end.
I have a Lumia 950 and I wanna to know about the audio quality under a Miracast connection: there is not `Connect` feature with Spotify Windows 10 mobile app and I've some trouble with the bluetooth connection with my Avr Marantz using Wi-Fi and bluetooth on my Lumia at the same time
(note that Lumia is bluetooth Apt-X compatible , the Avr Marantz not).
So a miracast device on a Marantz hdmi entry could be a good alternative. But let's talking about audio quality, thanks
For any serious Audio quality --FORGET Blue tooth -- not up to the job - especially if you want decent uncompressed audio (FLAC for example).
Go seriously for a WIfi speaker connection -- I'd suggest looking at some of the Bose wireless ranges. Also have a look at using something like Logitech media server (squeezebox server) for transmitting Audio. The actual squeezebox hardware devices have for a long time been discontinued by Logitech - but the server is still supported and can play into a load of decent High end Audio equipment.
Saying Blue Tooth and High quality Audio is like using the word Beer and Budweiser in the same sentence. !!!
Wifi will work for high quality Audio -- Blue tooth is a compromise - will be OK in some situations - but most definitely not for high quality sound.
