I currently use my oldoldold iBook G4 as a a craptastic laptop(can't afford any better), and I tend to watch a fair bit of Samba streaming XviD from my computer, and I'm just wondering,

If I open up the iBook, and it autoconnects to my home network,
then I plug in the ethernet cable,
then I CMD+K, connect to my computer, run a video in Quick Time.

At this point, over what interface is the video coming in on, WiFi, Ethernet, or each packet alternates between each? Or is it just some random choice thing that gets made?

Just shut down the wifi. Then you're sure that it runs over the physical network

_{once upon a midnight dreary, while i pron surfed, weak and weary, over many a strange and spurious site of ' hot xxx galore'. While i clicked my fav'rite bookmark, suddenly there came a warning, and my heart was filled with mourning, mourning for my dear amour, " 'Tis not possible!", i muttered, " give me back my free hardcore!"..... quoth the server, 404.}

From the lack of lag, it seems that the physical actually IS used, but I'm just wondering how the packets and everything gets organized.

Wait for Kyle, Bern or Bertster. They'll know

each network card wired or wireless has a mac address... so when it sends a request... that mac address is included in the packet
so when it gets to its destination it knows which mac adress to send it back to... that's a simple way to explain it... there are other things involved... but if you are using the wired connection... just disable the wireless

Love is the answer

Edit: Re-reading your post Catbox, that's not quite true. If the destination host is on a different network then the host originally sending the request, the source MAC address will be the router closest to the receiving host. A la, once a packet you send passes through your home router, the source MAC on the frame will be that of your router. The destination MAC will be your ISP's router, and once it gets there the source MAC will change to the ISP's router as it sends the frame to the next router, or destination host.

As to what interface is used, your computer will look for the most reliable interface. A copper wire is more reliable then an electromagnetic transmission so your computer will choose that one. That's the way windows does it, it actually makes sense, so I assume the Apple OS's do something similar. Not to mention that wired media allows the use of a simpler, more efficient protocol thus being faster then wireless, or at least has less overhead.

Edit2: Oh, and shut down your wireless connection. 'Tis a waste.

Most desktop operating systems weigh interfaces according to varying criteria. Usually it's strictly bandwidth, but with some, things like the type of interface is part of the path cost calculation. Try downloading Wireshark, and see what's going where.

By either regard, the ethernet cable wins unless you're using 802.11N and have a 100 megabit switch/router.

As far as I know even the G4 prioritizes, so what Defiance said. Although to be sure just do a simple test of shutting down the wireless, playing a video and as it plays turn the wireless on again. In theory, there should be no jumps / stops.
