[QUOTE="Scythe42, post: 576936, member: 95833"] Not voting as I know which DLL does what 'cause I compiled them. Hardware/Software: [LIST] [*]OS: Win7 x64 [*]CPU: E8400 @ 3.0GHz, passive cooling [*]GPU: Nvidia 9300 onboard /w driver 195.81 Beta (too lazy to update) [*]Memory: 4GB [*]Haali Splitter: high priority, increased buffer size, disabled search for linked files [*]MP: latest public SVN, process priority set to high, using refresh rate changer for 1:1 fps/Hz (except for 25p that uses 50Hz) [*]Plugins: only Moving Pictures and TV Series [*]Skin: StreamedMP /w weather and RSS disabled [*]Codecs: MPC for h264, ffdshow for SD, Nvidia Decoder for MPEG2, audio uses ffdshow (DTS, DD passthru) [*]TV: not using MP for watching TV [*]Connection: HDMI to DVDO Edge to Onkyo receiver to Samsung TV [/LIST] I consider my system a lower mid-range system because I used an ITX board with everything onboard and have no free slots for a faster GPU. I really like to have one of the new ATIs with HD audio passthru so I don't have to use multi channel FLACs for remuxed BRs. Test result: basically all the DLLs perform the same on my system including the SVN version in regards to playback quality. Nearly flat lines for SD, little jitter on HD (only drifting yellow line at 23.976 because Nvidia doesn't hold it correctly). Now and then a frame or two get dropped beside the first few when the DirectShow graph starts or the ones when using skipping steps. Mostly they are dropped due to external influences (maybe 1 or 2 per hour, on some material a few more). The few HD TS samples I have show a few more dropped frames when de-interlacing to 50p @ 1080 lines. But still no really jumping graphs in the stats renderer or a lot of dropped frames. VLC and MPC-HC show roughly the same amount of dropped frames here. [/QUOTE]
