I had reasonable success a while back streaming video (up to 1080p H.264) over
802.11a (would've done 802.11n, but the driver for the USB WiFi dongle I was
using didn't implement 802.11n support at the time...maybe that's since
changed). HD MPEG-2 recorded from TV was occasionally troublesome if the
bitrate started getting too far above 10-12 Mbps, but HD H.264 is generally no
more than 6-8 Mbps (unless you're trying to stream a Bluray rip that you've
not transcoded to a more reasonable bitrate).
One caveat: Matroska files stream pretty horribly from storage groups to
remote frontends. My observation was that it'd try to burst something like
15-20 seconds' worth of video through, then go idle. Over a wired network,
there's enough available bandwidth that this doesn't present a problem, but
over WiFi, this invariably caused frequent prebuffering pauses. Streaming
directly from a NAS box to the frontend over SMB wasn't any better; in fact, I
had been using that and switched to storage groups to see if they'd be any
better. I ended up repackaging most of my video as MPEG transport streams;
while these have more storage overhead in the NAS box, they stream more reliably.
(I ended up moving into a house about 6 months ago that was prewired by the
builder. w00t! The USB WiFi a/b/g/n dongle is now sitting idle; the 5-GHz
access point is serving mostly as a gigabit switch since the switch on my desk
died a while back and I've not gotten around to replacing it.)
