Lagging video problem (network?)

[spott]

Hey Guys.
I experienced a little lag when I stream video through the PS3 Media Server. The problem happens when an 720p in TsMuxer-mode video requires about ~ 15-20 Mb/sec - I really do not understand.

Connection from the PS3 to the network are: 55% (wireless)
My PC is connected to the network via cable.

PC Specs:
Intel Core2Duo E8400 3.0 GHz
GeForce 9800 GTX
2 x 2GB Kingston PC2-6400 (400Mhz)
Harddrive is 750gb Samsung 32mb cache 7200rpm

Vista Score: 5.6
5.9 in all categories except processor = 5.6

Are there any of you can see what the problem might be?
- Is the CPU or the wireless connection from PS3'en not good enough?

15Mbit and more is little bit unstreamable via WIFI. Theoretical WIFI throughput is 54Mbit but maximum is 10-15Mbit so now you know why it shutters when peak bitrate is higher than 10-15Mbits

Most probably the wireless. My server got lower specs than yours, yet there's no stutter, because both ends are wired via 1000mbit If you absolutely can't go wire then you could mess with the keyint, vqmax and vqmin settings, at the cost of CPU and perhaps quality

Thank you very much (:
I expected that it would be the problem.. so, ill try to connect via cable aswell and test it again.
