- MPC-HC + MadVR + Xy Subfilter + Reclock: With a pre-buffer of 500ms and a maximum latency of 8%, Reclock was able to maintain consistent audio playback of bitstreamed audio +/- 25ms either way. When using Reclock, it is recommended that all audio be converted to PCM over bitstream, but I am unable to notice any difference.


I tried the variants you have, but I am sure I read on a lot of places that Reclock and Passthrough audio is a waste of time. How can it adjust when it can't access it. It basically drops or dupes frames, which you can setup in XBMC.

You can actually use Reclock in XBMC with Dsplayer, but I bitstream, so again pretty pointless.

I suppose, and I have to add myself here, it's all well and good saying XBMC should do this and that, but like we both know MPC-HC needs Reclock as well, so its not just an XBMC issue.

I just reset everything today, changed the change refresh rate to match option, and today it seems fine. Just never know when it is going to start annoying me again.

I agree that PCM audio provides a more stable experience, but adding Reclock to a system that bitstreams does improve the situation. The comparable "sync audio to video clock" in XBMC is not nearly as effective - or in many cases, is ineffective. Reclock does work with bitstreamed audio provided the original refresh rate and playback rate are close. When bitstreamed auido is used, Reclock drops/dupes packets to keep sync with the video clock. Only when too many packets are dropped does playback suffer. With PCM streams, the decoded audio is sped up or slowed down to match the video refresh rate. This is considered the preferred but not the only method of correcting audio playback.

24p playback seems to be a common problem for HTPC's in general. I know Reclock is not a popular option with those obsessed with bitstreaming, but having an option to implement something similar in XBMC would make many people happy. I want smooth 24p playback with accurate audio sync above a pretty picture and bitstreamed logos on my receiver. I have read that Reclock can be configured to work with FFDShow, which makes me wonder if a similar technology could be added to DVD Player. J River Media Center is the only other home theatre backend I'm aware of that has has piggybacked off Reclock's code to create something it calls "Video Clock." With that said, I'd still happily return to DVD Player if the situation was improved. The picture quality differences between MPC-HC are noticeable but negligible.
