Purchased the mycloud over the weekend and I am totally impressed. I streamed a 1.2gb MKV file to my android phone over 3g this morning and it played beautifully. Is there any way I can use some kind of programme that shrinks the file size down on the fly before it gets to my phone? I have an unlimited data plan but if I want a show every day that’s quite a lot of data per month.
What you are looking for, is not directly supported in MyCloud.
For this to work, there should be a streaming server sitting in the MyCloud device, which can do adaptive streaming , which will be able to adpat to the optimal bit rate depending on your client device’s bandwidth. Technically, it is very much possible to build this kind of a streamer which can run in the MyCloud system.

Thanks for the reply. But looks very complicated. I think I will continue as I am. 
If you have a PC on your network, you can use Plex to stream local files from the cloud drive to remote phones, tablets, or computers. Works great and is very easy to set up.
The need of a turned on PC to do the job defeat the purpose of MyCloud, at least for me.
With a pc turned on i don’t need mycloud at all 
If a nas device needs local computer (hardware) and local software to do his network job is better to setup a server pc and get the job done.
