straightline: are u streaming via wireless or cable ? Are u streaming .MKV's ?
I had a core 2 duo laptop and it streamed 720p just fine to my ps3 using the ps3 media server, but 1080p wouldn't tho, lots of spikes and slowdowns... i'm guessing its 2 heavy on a core 2 duo cpu...
Anyways i found this link (
PS3 Media Server • View topic - mkv 1080p streaming - CPU 100% ) hope it helps you solve the problem. Be sure to check the rest of the forum and perhaps ask some questions there.. they seem to be nice folk :)
I do know the problem has something to do with remuxing and transcoding, but bcause thats not my area of expertise i can't really help you out :\ Try and figure out what those names mean and be sure to check their forums for extra information i'm sure u'll get to the problem quickly =)
