Windows 7 - Audio/Video Stutter/Hesitation

I'm currently using VGA, as to use HDMI causes audio feedback in the TVs speakers when there is no audio signal only video going into the tv. So stuck with VGA.

For my problem (only stutters for live music streams, not download or stored media), I'm using both VGA and HDMI (2 cards, 4 monitors - 2 are hdmi). I have a hard time believing the video cabling to be the issue when I can get a crystal clear Line In signal and immediately send it right out to the speakers, or perfect playback of downloaded or stored media. It's only on live streaming radio, on Windows 7-64. My IT guy confirmed it on 2 other Windows 7-64 PCs outside our network and compared them to Windows 7-32. The Windows 7-32 machines did NOT stutter.

Interestingly, I just tried some live video feeds (with audio) and they don't have this problem on my PC.

Just to add potential data points, I get stuttering, and I did on Vista as well.

I now run 32 bit Windows 7 Premium, and I have noticed that when I am watching I use about 40% of my CPU (2.6 Ghz AMD dual core) regardless of the window size in WMC or WMP. I just happened to be glancing at my CPU Meter gadget when I got stuttering earlier today, and I obviously don't know which was causative, but during the stuttering my CPU usage jumped to 100% or close to it during the time it was stuttering then dropped back down to 40%.

The overall duration, when it happens, is shorter and the stutter is faster in Windows 7 than it was on Vista. It seems to impact video and audio... If my Vista experience is equivalent to a person stuttering, in Windows 7 it is equivalent to someone rolling their r's.

It seems that mine happens mostly when watching TV (either live or recorded) but this could be because that is the media viewing I do most often is DVR playback or live tv.

OK, this is habby, and I'm pretty sure this is a microsoft problem. I am a video editor by trade. I use 2 computers so while one is cooking I can edit on the other. That way I can leapfrog thru my work. I had vista on both computers ever since it came out. I always kept my microsoft updates updated. All was fine until service pack 2 came out. There was that darn video stutter. It would hang when you hit the play button for 2 or 3 seconds then straighten out. I uninstalled service pack 2 and the stutter was gone on both computers. Then I did a clean install of windows 7 and there was the old stutter back. Whatever was in service pack 2 for vista must have already been installed on the windows 7 disc. We can only hope microsoft will fix it.

I have not done extensive testing yet, but Internet explorer 9 beta seems to have solved my video hesitation in pinnacl studio 14.

I too have the same problem. Just download the latest graphic driver, restart it and it solved.
