[QUOTE="ixian, post: 477701, member: 54932"] I've found in real-world use that a pretty decent CPU/Northbridge is needed to receive streams from a MP TV server using the HDPVR to a client, if we're talking about true 720p or 1080i streams from an STB. Even though the HDPVR compresses it via h.264 it's still a pretty high bitrate stream, in real time, that needs to be decoded and output after it's received over the network, in as near real time as it can be. That's quite different than, for example, receiving a prerecorded VC-1 or h.264 stream, because unlike live those can be buffered/read ahead. My AMD 4850e dual-core CPU wasn't up to the task, primarily due to it being HT 2.0 and not HT 3.0 (about 1gb difference in memory transfer speed in layman's terms). Only after I upgraded to a Phenom II CPU, which had the same cores/clock speed but supported HT 3.0, did my problems completely go away. I still believe, from what he's posted, that the OP has a different problem - it doesn't sound like he's far enough along to even know if he has performance issues yet :). If the CPU/NB/Memory wasn't up to the task he'd still get picture and audio, just with a lot of stuttering. [/QUOTE]
