I have been suing azul for a few years now. Always did the job and was good for streaming. However I just got an ipad3 and it crashes all the time. Cannot download over wifi, cannot press "done", cannot connect over Internet etc etc. all these things make it crash. Used to be able to download over Internet, but now reports that the certificate is out of date (???).
8player seems more stable, but play back is not nearly as good. It will download from my Netgear Stora NAS on my wifi but I can't get it setup to do over the Internet yet. Seems a fairly complicated setup.
8player does have an option to play file in another player. So at times I have downloaded using 8player, then played in azul.
I might try buzz.
Either way it is annoying. I can't find a player to play non apple formats well, and also download and stream well.
