One of the screens of 720p 24fps playback was from when I was still connected to my monitor and the measured refresh rate is different.The few things I did before the measured refresh changed was, revert to Generic PnP driver for monitor, remove monitor, remove DVI->VGA adapter on DVI port next to s-video port, connected TV to same DVI port.Onto the screens...  Two of them show recorded TV with and without reclock.  Without reclock, the NST gradually rises to around 20, then the video stutters, the NST drops back down, the red line spikes downward and then NST begins to climb again.  It does not report dropped frames when this happens.  With reclock, the NST stays steady and I don't seem to have the stutter/jitter, however there seems to be some audio sync and playback issues and I get no 5.1, just stereo.  I also can't seem to use the Media Center video and audio decoders.  When I do I get no audio at all.  Perhaps I'm not configuring it correctly?  Either way I find the need for something like reclock puzzling.  I'm watching US broadcast television on a US television.  Why can my TV do it but my HTPC can't?  How can these things NOT match up?With my measured refresh rate and actual refresh rate so close, why am I still seeing this problem?  And fyi, my actual frame rate's last few digits are always jumping around, but it usually reads a clean 60.00.Is this something all HTPC users have to deal with?If I change my refresh rate via Windows from 60Hz to 59Hz, the measured refresh does not change.  Why is this?My manual doesn't state, but are all CRT televisions locked at 60Hz or do some have other options?You will also notice that my render time is back down in these screens.  Sometimes the render times (green lines) DO show right next to the yellow line, but usually a seek/skip will clear that up and so will the NST hitting 20 and "resetting".  How can this be explained?I've also attached two screens of 720p 24fps playback.  Is that super spikey red line normal?  The red line occasionally breaks cadence but it's usually consistant.  Again, no apparent difference in playback between 60Hz and 59Hz.  From what I've learned as of late, I should expect this on a 60Hz television.  Is there any way to make it better?What is MaxLine and PCD in the video information overlay?I know there are a lot of questions in here, sorry.  But I feel like I've made some progress thanks to all of your help.  And hopefully this thread will help someone else in the future.Thanks again,Mike</blockquote>
