What's the system chugging on, the streaming network bandwidth? In other words, the video itself is fine as it is (or if using Mencoder, it's been successfully transcoded) but my network just can't handle that big of a file? I found myself going down to 25/7/x (I don't remember the third value in the manual configuration dropdown list) in order to fluidly stream 1080p from my laptop, but I suppose that only worked because the quality was transcoded to a low enough quality that the bitrate was acceptable on the network? I'm wired from router > PS3 but I may just have to wire up the laptop tonight and see if I can change that from 25/7 to 25/2, or even 3/2 if I'm feeling lucky.
If you have an h.264 video that is compatible with the PS3 in a container the PS3 doesn't support (such as MKV), PMS will demux the audio/video streams and present them to tsMuxeR to remux into a TS container that the PS3 supports, losing no video quality and depending on the settings/audio codec, it can keep the original audio intact.
If the video isn't compatible, then you'll need to transcode the video. decoding 1080p takes a lot of CPU time, even on high end systems. mencoder_mt will help somewhat, in that it'll allow for multiple threads for decoding x264 videos.
Do you have the checkbox checked to use tsMuxeR if compatible video detected? The thing to then look at is if you hit select while the video is playing it should say in the upper righthand corner "MPEG2" or "AVC". If it says AVC it is streaming w/ tsMuxeR. If it says "MPEG2" it is transcoding the video.
In either case, streaming 1080p over wireless is going to be very choppy. Definitely try hard-wiring the laptop.
mencoder does not currently support GPU offloading. Even if it did, most onboard video cards will not be of any use for this. I believe you might be able to configure PMS to use Avisynth (and perhaps you can then use coreAVC for some acceleration). Someone else might be able to give you more info on that. But, again, you probably won't be able to use GPU offloading with the onboard video.
