It sure looks spot on to both me and my wife. Are you having problems in that area? Can't even run a calibration test for this because of another XMC-1 bug that cuts audio... |

FTR, there is absolutely nothing preventing either TCP by using the option TCP timestamps or the application itself to calculate the delays over the network connection.

FTR. TCP timestaps are not for calculating single-direction delays and there is nothing there to help with that. It's intent is faster mechanisms of recovery from packet losses.

All I know is that LOVE the sound quality I'm getting. Much better than the local Regal Cinema theater.
Back to your previously scheduled IgorZep programming.

I don't notice any issue with the lip sync and my XMC-1. Everything appears spot on. If there is a problem, I'm not hearing or seeing it.

Just because you dont understas how it can be done does not make it impossible. Just because you don't understand the technology and what are the limitations doesn't mean there are none. |

But just because you can't see it or hear it doesn't mean that there isn't some serious, serious problem you just are not grasping. Are you sure that it isn't .0000001 millisecond off? My suggestion is to use the Force and see if you experience any disturbance.  |

Before this thread becomes too terribly personal, I'm going to ask that all participants remain civil and respectful in their tone, and if you've forgotten the "Lounge Rules of Etiquette", please review them before you post again. This post isn't aimed at any one member, but it is an attempt to keep what I've experienced in the past as a moderator from becoming a full blown thread full of personal attacks and I won't be posting in this thread any more reminders on this subject. Thank you, in advance, for your cooperation!!!  |

I am no where near understanding some of the technical issues involved. All I can go by is what I see and hear and in that regard, everything seems fine to me. |

I've never noticed any lip sync issues with any content when using my cable box or my Oppo.

I can appreciate having manual a/v lipsync specifically in a video processor [ like my old dvdo duo with per input adj ] but even this was hit and miss with trying to line up the frames with the audio . Not up to igor's standards methinks  The nice thing about the xmc1 is theres no video processing so hdmi protocols can do whats needed ; if the other component follows its edid properly of course  Wondering if your running multiple frame rates foggy and some video processing is upscaling/delaying etc ? Set everything to 480i/60 as an experiment maybe or 1080i say to utilise the xmc1s bandwidth capability ; whatever suits.. |

I'm curious as to what real world issues the OP is having with the XMC-1, not with the design, implementation and lack of documentation but how it actually sounds. There must be something, other than wanting to verify everything is "perfect," that he noticed while listening that is causing his dissatisfaction and desire to re-design Dirac and the XMC-1. I think Keith has given a very detailed explanation of what can and cannot be done using Dirac with the XMC-1. While the OP might not like it, it is what it is. Of course suggestions can be made, but it sounds like what is desired is beyond the scope of the Dirac/XMC-1 collaboration.
