I have just bought a new Logitech QuickCam 5000. I installed the software exactly as recommended, rebooted, and plugged in the camera to my USB2 port. It was immediately recognised, and all seemed to go well. I made a test recording but was disappointed to find on play back, very soon the sound and picture went slightly out of synch; (the sound being fractionally ahead of the picture). This never happened on my "old" Logitech QuickCam Express.
I contacted Logitech support by e-mail, (apparently the only way possible), and their reply seemed only to apply if the software failed to install; (and this advice did not work anyway).
If you have broadband, (it is a 3Mb wmv file), you can see what I mean here:
Just had a look at your clip, it started off in synq but lost it as it went on. It also froze Nero viewer on my PC and I had to hit con-alt-del to escape, which also closed my browser. Have you checked for Virus`s ?
Audio Tuning Wizard and AEC. Yes;, ran the wizard, and tried with and without AEC.
Yes, have checked the Logitech site, no relevant information there. I contacted their support via the web site, but their reply seemed only to apply where there was a problem in installing the software. I informed them of this, and awaiting a further reply. Their support is somewhere on the continent, not in the UK.
