I'll try to keep it short:
I have a new Insignia LCD TV, and connected to it is my PS3 and my cable company's DVR, both of them via seperate HDMI cables.
My PS3 has no issues whatsoever - Netflix, games, and DVDs run and play perfectly with perfect sync.
The DVR box is the issue - the audio sync is very bad, even with recorded shows saved on its hard drive.
I've tried swapping out both cables between the two devices, and using all 3 different inputs on my TV but to no avail.
Any help is greatly appreciated!!!!!
