HTPC Case: Antec Fusion V2
Cooling: Scythe Mini Ninja
Power Supply: Antec 430W
Remote: MCE Remote
TV: CRT + Panasonic PT-AX200 projector
TV - HTPC Connection: Sub-D + DVI

Video is slightly lagging behing audio with both MEPG2 and H.264 material. This happens with and without the new Reclock. I notice this with 24, 50, 60 Hz material, and also if I watch video using MPC HC.

The difference of audio and video is so slight, that I think most people would be happy with that. However I'm very allergic to even small problems with lip sync, and I'd appreciate any tips how to get perfect sync for audio and video.

You are using optical connection from your HTPC to your AVR ?

You can check if your AVR has settings for audio delay.

Unfortunately it does not support. I'm using coaxial output.

And you are using SPDIF also?
I'm having the same problem as putkonen.

But i guess it doesn`t make a big difference

This is in another thread how I solved audio sync issues with 24hz playback with spdif - mostly with dts tracks but not on all videos?! I guess you could give it a try..
