Im having a few problems when playing movies from my NAS drive, my network is connected up as follows.

Upstairs spare bedroom (man cave) has my main computer with Virgin media Super hub, the Super hub has my computer, sons room and Ethernet cat 5e cable to living room.

In the Living room I have a Netgear GS108 gigabit switch which has connected to it TV, PS3, Xbox 360, Bluray player, WDTV Live and a Synology DS210J.

As its set up at the moment playing a film on the WDTV Live from the NAS drive some high bit rate films pause and have to buffer, if I move the NAS drive upstairs and connect it to the Super Hub the same films play fine even though the NAS drive is now about 15 meters cable length further away than it would be connected to the Netgear switch.

Anyone got any idea why im having this problem, I though having the NAS drive close to the WDTV Live (on the same switch) would work better than having the NAS drive in a different room with an extra 15m or cable ?
 
The NAS is in a bottleneck as the wdtvlive and nas are using some bandwidth at the same time.

Put the nas directly into a port on the router and leave it there.

I'm sorry but that makes no logical sense ... the bandwidth usage is going to be the same in each case (as originally you have NAS -> GS108 -> WDTVLive and in the alternative case you have NAS -> Superhub -> GS108 -> WDTVLive ... i.e. the amount of traffic flow across the GS108 from the NAS to the WDTVLive is the same just the input port on the GS108 will differ due to it being sourced via the Superhub instead of directly from the NAS).

I'd be checking that the NAS is actually remaining sync'ed to the GS108 at a gigabit connection. I know one of my QNAP NASes has a tendency to drop back to 100Mb/s if it's connected to a GS108. Maybe the OPs NAS is doing this but doesn't drop back if it is connected to the Superhub.
 
Thanks for the replies guys, Ill have a look to see if the NAS is keeping its gigabit connection, ive even tried swapping ports of the GS108 in a vain hope it may solve the problem ...but it didn't.

Yep I could leave it connected to the Superhub in my "man cave" all the time but would rather it be in the living room with all of my AV gear and I cant for the life of me see why it shouldn't work connected directly to the GS108.
 
As I see it the data from the nas has to go all the way up to the router and back through the switch to the wdtv, them being on the same switch isn't worth anything. So as said, move the nas upstairs :-)

If I understand rightly connecting the nas to the superhub resolves the problem?

Yes, if I connect it to the superhub the problem goes away, ie ...NAS-> GS108-> WDTV causes the problem, .......NAS-> Superhub -> 15m cable-> GS108-> WDTV Live no problem at all.

You would think the problem would be the other way round with the extra cable length coming into play, I have an old Linksys router I could use as a switch, I think ill try it in place if the GS108 to see if I still get the problem.
 
OK, ive just tried a netgear FS108 (10/100) I have and that works fine,cant understand why I have the problem with the GS108 (gigabit)

Erm why would it do that ... the OP states that both the NAS and the WDTVLive were on the GS108 ... traffic should just be internal to the switch (in the original configuration) without the Superhub coming into it.
