[QUOTE="ixian, post: 480516, member: 54932"] What are your bandwidth rate settings (constant or variable, how high, etc) for the HDPVR, and what codec are you using to play it? Also, believe it or not, those system specs may (may) be just a little too low to stream live HDTV from the HDPVR. I know what you're thinking - BD, etc work fine, the HDPVR is h.264, so why not it? But it isn't the same thing. Here, we're talking about a live HD feed streaming in real time. I have two clients, one an AMD platform, one Intel, streaming from my TV server. The Intel client (2.5ghz P9500, dual core, 6mb, 4500HD video) has never had a problem. The AMD client (780g, 4850e 2.4ghz dual core) always had minor issues, stuttering, the occasional freeze, etc - I agree, it drives you nuts. The difference between the two is, the AMD has a faster video chipset but slower CPU. MSI finally released an update for my AMD motherboard supporting Phenom II's, which in addition to being faster CPU's also support Hyperthreading 3.0, which offers significantly improved memory bandwidth. After updating it I popped a faster CPU in to the box and my issues disappeared. In my experience, HDPVR streams in MePo benefit greatly from CPU power, far more so than video. Codecs play a big role too. With MePo 1.02 and below, there's really only two choices - the Arcsoft TMT codecs, or PowerDVD 8.0 (9.0 doesn't work). You can read earlier in this thread about getting and installing the latter. I found the PDVD 8 h.264 codec provided a superior picture and less stuttering than the Arcsoft. CoreAVC works as well as a codec but I had major issues with lip-sync using that one - however I have an ATI video chipset, since you are using nVidia you may be able to use CUDA since CoreAVC supports it, which I hear offers incredible performance gains. MePo 1.1 may or may not have fixed the tsreader bug that among other things caused other codecs, like MPC, to not show up under TV options, but I haven't tried it yet. Finally, there's refresh rates - you may want to give the Dynamic Refresh Rate setting in MePo a try. I recommend visiting this thread: [url]https://forum.team-mediaportal.com/mediaportal-1-talk-45/automatic-refreshrate-changer-44338/index62.html#post407252[/url] , use the Excel spreadsheet he posted - it's very easy, he set everything up so all you have to do is enter the refresh rates your display supports and it will pop out the settings to paste in to MePo - and see if that helps. I got rid of some minor stuttering that appeared on some channels by doing that (plus my regular videos play smoother, it really helps a lot depending on your display). So to sum all that up: Check your codecs and try a different one. Use the dynamic refresh rate changer (it's in the MePo config under General) If all else fails, throw more hardware at it in the form of a faster CPU. [/QUOTE]
