Adding a WiFi media player to a home network

[#1]

Just quick follow-up: it occurred to me to try streaming a few video files on my Acer Aspire netbook via the wireless connection to one of my desktop PCs, and comparing the performance with my new Dune media player.  It was a bit of an eye-opener.  Here's a typical result:
A 9.83GB MKV file launched on my netbook in less than four seconds.  On the Dune it took just under twelve minutes.  Same source, same distance.

Does the notebook start playing as soon as the buffer is full whereas the Dune waits for the complete file?

That's an interesting question; I don't know.  I'll check and see.

Well, that was an eye-opener: things have changed completely.  Files which yesterday were taking minutes to start playing are this morning coming up in seconds.  The largest I tried, a 9.83GB MKV file, took over half an hour last night (at which point I abandoned the exercise): just now it started up in five seconds.
Spraxyt, it's  exactly as if the Dune was waiting for the buffering to complete yesterday but today is not: but I've changed nothing.  And curiously, last night I tried the TV101's built-in YouTube browser: everything there came up almost at once as well.  The problem, whatever it was, seemed to be only between my PC files and the Dune.
Today, it's like using a different piece of kit.  Which is strange, but pleasing.

Sounds like the media files are now cached on the Dune and don't need reloading.

I wondered about that, but the TV101's built-in file navigation includes a location option labelled Dune which is reported as being empty.  Still, perhaps I'm misreading things.
I'll try adding a new file to one of my desktops and seeing how the Dune performs with that.
Thanks for the thought.
