I have done research for the past three days and this is a problem that's been hunting me, I went out and I bought a Linksys EG008W 8 Port Gigabit Switch to updated my 100M/bit Network,Because I wasn't able to play 1080p videos, because the videos would stutter, so I figured it was the network. I also have a Western Digital Mybookworld 750Gb Hard Drive (Where I keep my media files) on the Switch (External HD is also Gigabit Ethernet 1000Mbits/s), The PS3 Also 1000Mbits/s, and My Imac which I bought a few months ago 1000Mbits/s and I have the Ip Manual and on 1000bt/ Full Duplex (Model Name:iMac,Processor Name:Intel Core 2 Duo,Processor Speed:2.8 GHz,Total Number Of Cores: 2,L2 Cache:6 MB, Memory:2 GB,Bus Speed:1.07 GHz). All of this equipment HD, PS3, IMAC, go to the gigabit switch on a Cat6 cable. I tried to play the 1080p videos, and they still stutter. I have played with different configrations on the Mencoder, (Crazy bit rate, Low Quality poor CPU) I Even put a 1080p video on the Imac's hard drive to see if the external hd was lagging, but it makes no difference. It Stutters. For the past three days I've noticed that some had a similar problem, and I've tried some of the solutions provided like increasing the Keyint: to 25 and 50 with no luck. So I have two questions for this great community. 1. Can anyone help me by offering some suggestions on why my files stutter??? 2. From previous post I learned that "keyint" manages bit rate, but what do the others do (vqscale, vqmin) ?? Also the files seem to do much much better on a pc laptop that I have dual core 1.5ghz with 100mbit network card. I get to the first 7 min without stuttering. I have tried to use the same settings on that ps3 media server app on the pc to the imac, but it makes no difference. And for all of you that are in the 1080p streaming quest thru ps3 a good file to test your 1080p stream is with the file elephants dream hd. 10 min file that will rock the hell out of your network is so detailed packed, I see that file as the ultimate test.
****Please help****** !!
