Hi. I just installed NPVR today, and have been playing around with it much of the day. I have a Win7 64-bit system based on the ASRock H61M/U3S3 mobo, 8G RAM, AMD HD6850 video card, and core i3-2100 CPU. So, not the latest-greatest PC, but a pretty capable machine, usually. I have played a wide variety of 3d games on it, and it has always worked well for me, so performance has not usually been a problem for me.
So, anyhow, I believe that video card is supposed to have a built-in hardware-accelerated MPEG and H.264 decoder? In NPVR, one of the available decoders for those two codecs, is "AMD Decoder". I tried that, and at first it seemed to be working fine, but whenever I would try to jump forward or backward in the timeline of the video, there would seem to be a long delay before the video would start playing, and it would start playing in the wrong place, and run super fast until it caught up, then sometimes it slows way down and doesn't keep up with the audio, and then the playback eventually hangs. When this happens, pausing, waiting a few seconds, and unpausing, SOMETIMES gets playback to resume at the point I paused, at normal speed and in sync with audio. Sometimes, I had to close NPVR and restart it.
I have a number of other codecs available on my PC, including Microsoft, Cyberlink PowerDVD, AverMedia (must have been installed by my TV tuner card when I installed drivers) - and all those seem to work fine and not have the same problem.
I find it rather surprising that, apparently, software decoders are performing much better than the hardware decoder (at least, if that AMD Decoder is actually supposed to be the hardware decoder on my GPU). Has anyone else run into problems with the AMD Decoder?
