I think that needs helper software running on a PC. Can you access a nas directly with it like the op wants to do?
Yes, Rich, it does need helper software running on the PC, but that has no additional cost; one buys the VLC Streamer mobile app for two bucks and then downloads the helper software from the creator’s website. Programs do need to be running on a PC: it’s just the way things have to work today – until WD creates something similar for the media players so the media player can play and wirelessly transmit the video instead of VLC Streamer & VLC on a PC!
It can access any drive that is shared; e.g. ones on the WD, ones on computers, ones as standalone NAS, etc. It even can access drives on the Pogoplug, that can not be shared as a typical drive but are connected to the router’s network.
If you haven’t tried this app yet, RichUK, you ought to – it is a UK product! I can stream ISO files, MKVs and, of course , mp4/m4v files to my iPads (Gen 1 and Gen 3), so how cool is that! Some ISO and MKV video files are “too much” for the apps, so they experience buffering. Even so. enough do stream OK without buffering so that it is definely a cool app.
