Last week I threw up my hands and went all wired to my PC and devices. I share a home which belongs to my housemate and was using her 11G router to connect the stuff in my room to the net (PS3, Xbox 360, TiVo Series 3 and my notebook). I got interested in streaming video when they added new codec support for the Xbox and new streaming support for the PS3. I'd been trying to stream 1080p and 720p AVC clips (mostly taken from Apple's QuickTime Guide site), which wouldn't work well at the maximum rate that I was getting from 802.11G. So I asked my housemate whether she wouldn't mind if I moved the cable modem and router from her room into mine--she only has a notebook on the net, used wireless. Now that I've done that I'm getting 12-15Mbps downloads from the net from some sites and who knows how fast transfers are going across my LAN (I also learned a vital lesson about the importance of CAT6 versus CAT5e cabling in 100MHz and GHz wired networking--replacing a CAT5e cable with CAT6 tripled
my network download rate--I was maxing out at about 4.5Mbps using a CAT5e cable between my PC and router.
1080p clips run great across my wired LAN, both to the PS3 and the Xbox 360.
On the PS3, you can tell whether you're getting a transcoding or not by selecting an item that you know is stored as HD with the triangle key and looking at the information for the file. It will tell you what the resolution is--it's a clue when it's 400-something by 300-something
. I set up TVersity to not trancode to reduce resolution, which it does by default.
