Hi guys - I need some help here, I have been desperately trying to get smooth playback of 23.976/24fps content on my PC (output to 24hz HDTV) - typically 1080p MKVs. Specs are Windows 7, Nvidia GTX 480, i5 2500k overclocked, so PC is more than capable. Using ffdshow software video decoding, madvr, mpc-hc etc so PC hardly breaks a sweat.

I have found that madVR in MPC-HC using exclusive fullscreen mode gives overall the smoothest playback (and trust me, I've tried everything - all combinations of players and renderers). But it still is not perfect. It still visually skips every 20-30 seconds or so - even though madVR with Ctrl + J info shows NO dropped frames! Sometimes it takes longer to happen though - maybe 1-2 minutes... but it's visibly there for sure - watching credits is a good test. Reclock enabled or disabled seems to make little difference. My graphics card has two options for output - 23hz (which madVR reports as ~23.974hz, and 24hz, which madVR reports as 23.999998hz. Which I choose also makes little difference - both have the similar stutter. Best way to describe it is it 'jumps' for a split second.

I seem to be at a dead end as to what is causing it. Any suggestions?
