hi everyone.. i wanted some feedback on using my htpc with true 23.976 fps
i have the setup below and running movies at 23hz (23.976 fps) i get a quick hicup/sutter every couple of minutes.. had people over they didnt notice but im the nerd and since i knw what to look for.. so wondering if anyone has feedback or can tell me if something is wrong in my setup
win7 x64 (home premium)
amd x3 450 (triple core)
nvidia gt430
4gb RAM
Onkyo sr-5508 preamp
Epson 8700ub projector
MPC-HC with ffdshow codecs (video out is YV12 and audio is bitstream)
dual monitor setup (main is vga output-LCD at 60hz other is HDMI to preamp/projector 23hz)
i have the hdmi from video card going to an onkyo preamp - from the preamp hdmi output to the projector
i have mpc-hc/ffdshow sending bitstream audio to the preamp
MPC-HC is running in overlay mixer mode
i get the projector to read 23.97hz under signal info and MPC to read 23.97 as well.. but again the hicup happens every minute or 2 (which last a second or less)
i tried enabling/disabling 4:4 pulldown and same thing..
I also enabled/disabled lip sync on my preamp and same thing (since i have a long run b/w htpc/preamp/projector the calucated distance is 120ms)
when i run the projector in 59 or 60hz ..i get no hicup but my goal is to run it at native frame rate
i checked my CPU/RAM usage during playback it varies b/w 12-18% on CPU and 20-22% on RAM ..so i dont think its a matter of slow CPU or not enoug RAM
so looking for any feedback? thanks!!
